4D.IMAPTransporter.new()

4D.IMAPTransporter.new( server : object ) : 4D.IMAPTransporter

Parameter	Type		Description
server	object	→	Mail server information
Result	4D.IMAPTransporter	←	IMAP transporter object

Description

The 4D.IMAPTransporter.new() function configures a new IMAP connection according to the server parameter and returns a new transporter object. The returned transporter object will then usually be used to receive emails.

In the server parameter, pass an object containing the following properties:

server	Default value (if omitted)
.acceptUnsecureConnection : boolean true if Qodly is allowed to establish an unencrypted connection	False
.accessTokenOAuth2: string .accessTokenOAuth2: object string string or token object representing OAuth2 authorization credentials. Used only with OAUTH2 `authenticationMode`. If `accessTokenOAuth2` is used but `authenticationMode` is omitted, the OAuth 2 protocol is used (if allowed by the server). Not returned in the `IMAP transporter` object.	none
.authenticationMode : string - the authentication mode used to open the session on the mail server	the most secure authentication mode supported by the server is used
.checkConnectionDelay : integer - the maximum time (in seconds) allowed prior to checking the connection to the server	300
.connectionTimeOut : integer - the maximum wait time (in seconds) allowed to establish a connection to the server	30
.host : string - the name or the IP address of the host server	mandatory
.logFile : string - the path of the extended log file defined (if any) for the mail connection	none
.password : string User password for authentication on the server. Not returned in the `IMAP transporter` object.	none
.port : integer - the port number used for mail transactions	993
.user : string - the user name used for authentication on the mail server	none

Warning: Make sure the defined timeout is lower than the server timeout, otherwise the client timeout will be useless.

Result

The function returns an IMAP transporter object. All returned properties are read-only.

The IMAP connection is automatically closed when the transporter object is destroyed.

Example

var server : object
var transporter : 4D.IMAPTransporter
var status : object
var info : string

server = newObject()
server.host = "imap.gmail.com" //Mandatory
server.port = 993
server.user = "qodly@gmail.com"
server.password = "XXXXXXXX"
server.logFile = "LogTest.txt" //log to save in the Logs folder

transporter = 4D.IMAPTransporter.new(server)

status = transporter.checkConnection()
if(not(status.success))
   info = "An error occurred: "+status.statusText
end

.acceptUnsecureConnection

.acceptUnsecureConnection : boolean

Description

The .acceptUnsecureConnection property contains true if Qodly is allowed to establish an unencrypted connection when encrypted connection is not possible.

It contains false if unencrypted connections are unallowed, in which case an error in returned when encrypted connection is not possible.

Available secured ports are:

SMTP
- 465: SMTPS
- 587 or 25: SMTP with STARTTLS upgrade if supported by the server.
IMAP
- 143: IMAP non-encrypted port
- 993: IMAP with STARTTLS upgrade if supported by the server
POP3
- 110: POP3 non-encrypted port
- 995: POP3 with STARTTLS upgrade if supported by the server.

.addFlags()

.addFlags( msgIDs : string , keywords : object ) : object
.addFlags( msgIDs : integer , keywords : object ) : object

Parameter	Type		Description
msgIDs	collection	→	Collection of strings: Message unique IDs (string)
msgIDs	string	Unique ID of a message
msgIDs	integer	kIMAPAll: All messages in the selected mailbox
keywords	object	→	Keyword flags to add
Result	object	←	Status of the addFlags operation

Description

The .addFlags() function adds flags to the msgIDs for the specified keywords.

$seen	boolean	true to add the "seen" flag to the message
$flagged	boolean	true to add the "flagged" flag to the message
$answered	boolean	true to add the "answered" flag to the message

The custom flags names must respect this rule: the keyword must be a case-insensitive string excluding control chars and space and can not include any of these characters: ( ) { ] % * " \

For a keyword to be taken into account it has to be true.

The interpretation of keyword flags may vary per mail client.

 server = newObject()
 server.host = "imap.gmail.com" //Mandatory
 server.port = 993
 server.user = "qodly@gmail.com"
 server.password = "XXXXXXXX"

 transporter = 4D.IMAPTransporter.new(server)

  //select mailbox
 boxInfo = transporter.selectBox("inbox")

  //get collection of message unique IDs
 mailIds = transporter.searchMails("subject \"New feature:\"")

  // copy found messages to the "documents" mailbox

.createBox( name : string ) : object

Parameter	Type		Description
name	string	→	Name of the new mailbox
Result	object	←	Status of the mailbox creation operation

Description

The .createBox() function creates a mailbox with the given name. If the IMAP server’s hierarchy separator character appears elsewhere in the mailbox name, the IMAP server will create any parent names needed to create the given mailbox.

In other words, an attempt to create "Projects/IMAP/Doc" on a server in which "/" is the hierarchy separator character will create:

Only the "Doc" mailbox if "Projects" & "IMAP" already exist.
"IMAP" & "Doc" mailboxes if only "Projects" already exists.
"Projects" & "IMAP" & "Doc" mailboxes, if they do not already exist.

In the name parameter, pass the name of the new mailbox.

var options, status : object

options = newObject()

options.host = "imap.gmail.com"
options.user = "test@gmail.com"
options.password = "XXXX"

transporter = 4D.IMAPTransporter.new(options)

status = transporter.createBox("Invoices")

if(status.success)
	info = "Mailbox creation successful!"
else
	info = "Error: "+status.statusText
end

.delete()

.delete( msgsIDs : collection ) : object
.delete( msgsIDs : integer ) : object

Parameter	Type		Description

The .delete() function sets the "deleted" flag for the messages defined in msgsIDs.

In the msgsIDs parameter, you can pass:

a collection containing the unique IDs of the specific messages to delete, or
the kIMAPAll constant (integer) to delete all messages in the selected mailbox.

Executing this function does not actually remove messages. Messages with the "delete" flag can still be found by the .searchMails() function. Flagged messages are deleted from the IMAP server with the .expunge() function or by selecting another mailbox or when the IMAP transporter object (created with 4D.IMAPTransporter.new) is destroyed.

Returned object

The function returns an object describing the IMAP status:

Property		Type	Description
success		boolean	true if the operation is successful, False otherwise

 server.port = 993
 server.user = "qodly@gmail.com"
 server.password = "XXXXXXXX"

 transporter = 4D.IMAPTransporter.new(server)

  //select mailbox
 boxInfo = transporter.selectBox("Inbox")

  //get collection of message unique IDs
 mailIds = transporter.searchMails("subject \"Reports\"")

  // Delete selected messages
 status = transporter.delete(mailIds)

  // delete all messages in the current mailbox
 status = transporter.delete(kIMAPAll)

.deleteBox()

.deleteBox( name : string ) : object

Parameter	Type		Description
name	string	→	Name of the mailbox to delete
Result	object	←	Status of the mailbox deletion operation

Description

The .deleteBox() function permanently removes the mailbox with the given name from the IMAP server. Attempting to delete an INBOX or a mailbox that does not exist will generate an error.

In the name parameter, pass the name of the mailbox to delete.

The function cannot delete a mailbox that has child mailboxes if the parent mailbox has the "\Noselect" attribute.

All messages in the deleted mailbox will also be deleted.

The ability to delete a mailbox depends on the mail server.

options = newObject()

pw = "XXXXXX" //password

options.host = "imap.gmail.com"
options.user = "test@gmail.com"
options.password = pw

transporter = 4D.IMAPTransporter.new(options)

// delete mailbox
name = "Bills"+transporter.getDelimiter()+"Nova Orion Industries"

// Purge all messages flagged as deleted
status = transporter.expunge()

.getBoxInfo()

.getBoxInfo({ name : string }) : object

Parameter	Type		Description
name	string	→	Name of the mailbox
Result	object	←	boxInfo object

Description

The .getBoxInfo() function returns a boxInfo object corresponding to the current maibox, or the mailbox name. This function returns the same information as .selectBox() without changing the current mailbox.

In the optional name parameter, pass the name of the mailbox to access. The name represents an unambiguous left-to-right hierarchy with levels separated by a specific delimiter character. The delimiter can be found with the .getDelimiter() function.

[].id	string	Unique mailbox identifier. Returned if withBoxInfo=true

If the account does not contain any mailboxes, an empty collection is returned.

If there is no open connection, .getBoxList() will open a connection.

If the connection has not been used since the designated connection delay (see 4D.IMAPTransporter.new), the .checkConnection( ) function is automatically called.

Example

 var server : object
 var transporter : 4D.IMAPTransporter
 var boxList : collection
 var info, split : string
 transporter = 4D.IMAPTransporter.new(server)

 boxList = transporter.getBoxList()

 forEach(box,boxList)
    if(box.interesting)
       split = splitString(box.name,transporter.getDelimiter())
       info = "New emails are available in the box: "+split[split.length-1])

msgID, a string value indicating the unique ID of the message to retrieve.

The optional options parameter allows you pass an object defining additional instructions for handling the message. The following properties are available:

Property	Type	Description
updateSeen	boolean	If true, the message is marked as "seen" in the mailbox. If False, the message is not marked as "seen". Default value: true
withBody	boolean	Pass true to return the body of the message. If False, only the message header is returned. Default value: true

The function generates an error and returns Null if msgID designates a non-existing message,

If no mailbox is selected with the .selectBox() function, an error is generated,

If there is no open connection, .getMail() will open a connection the last mailbox specified with .selectBox()`.

Result

.getMail() returns an Email object with the following specific IMAP properties: id, receivedAt, and size.

Example

You want to get the message with ID = 1:

 var server : object
 var info, mail, boxInfo : variant
 var transporter : 4D.IMAPTransporter

 server = newObject()
 server.host = "imap.gmail.com" //Mandatory
 server.port = 993
 server.user = "qodly@gmail.com"
 server.password = "XXXXXXXX"

  //create transporter
 transporter = 4D.IMAPTransporter.new(server)

  //select mailbox
 boxInfo = transporter.selectBox("Inbox")

  //get Email object with ID 1
 mail = transporter.getMail(1)

.getMails()

.getMails( ids : collection { , options : object } ) : object
.getMails( startMsg : integer , endMsg : integer { , options : object } ) : object

Parameter	Type		Description
ids	collection	→	Collection of message ID

Description

The .getMails() function returns an object containing a collection of Email objects.

First Syntax:

.getMails( ids { , options } ) -> result

The first syntax allows you to retrieve messages based on their IDs.

In the ids parameter, pass a collection of IDs for the messages to return. You can get the IDs with .getMail().

The optional options parameter allows you to define the parts of the messages to be returned. See the Options table below for a description of the available properties.

Second syntax:

.getMails( startMsg , endMsg { , options } ) -> result

The second syntax allows you to retrieve messages based on a sequential range. The values passed represent the position of the messages in the mailbox.

In the startMsg parameter, pass an integer value corresponding to the number of the first message in a sequential range. If you pass a negative number (startMsg <= 0), the first message of the mailbox will be used as the beginning of the sequence.

In the endMsg parameter, pass an integer value corresponding to the number of the last message to be included in a sequential range. If you pass a negative number (endMsg <= 0), the last message of the mailbox will be used as the end of the sequence.

The optional options parameter allows you to define the parts of the messages to be returned.

Options

Property	Type	Description
updateSeen	boolean	If true, the specified messages are marked as "seen" in the mailbox. If False, the messages are not marked as "seen". Default value: true
withBody	boolean	Pass true to return the body of the specified messages. If false, only the message headers are returned. Default value: true

If no mailbox is selected with the .selectBox() command, an error is generated.

If there is no open connection, .getMails() will open a connection the last mailbox specified with .selectBox().

Result

.getMails() returns an object containing the following collections:

Property	Type	Description
list	collection	collection of `Email` objects. If no Email objects are found, an empty collection is returned.
notFound	collection	collection of: first syntax - previously passed message IDs that do not exist second syntax - sequence numbers of messages between startMsg and endMsg that do not exist An empty collection is returned if all messages are found.

Example

You want to retrieve the 20 most recent emails without changing their "seen" status:

 var server,boxInfo,result : object
 var transporter : 4D.IMAPTransporter

 server = newObject()
 server.host = "imap.gmail.com" //Mandatory
 server.port = 993
 server.user = "qodly@gmail.com"

  //create transporter
 transporter = 4D.IMAPTransporter.new(server)

  //select mailbox
 boxInfo = transporter.selectBox("INBOX")

  if(boxInfo.mailCount>0)
	// retrieve the headers of the last 20 messages
	// without marking them as read
    result = transporter.getMails(boxInfo.mailCount-20,boxInfo.mailCount,\
     	newObject("withBody",false,"updateSeen",false))

.searchMails()

.searchMails( searchCriteria : string ) : collection

Parameter	Type		Description
searchCriteria	string	→	Search criteria
Result	collection	←	collection of message numbers

Description

This function is based upon the specification for the IMAP protocol.

The .searchMails() function searches for messages that match the given searchCriteria in the current mailbox. searchCriteria consists of one or more search keys.

searchCriteria is a string parameter listing one or more search keys (see Authorized search-keys below) associated or not with values to look for. A search key may be a single or multiple items. For example:

SearchKey1 = FLAGGED
SearchKey2 = NOT FLAGGED
SearchKey3 = FLAGGED DRAFT

Matching is usually not case-sensitive

If the searchCriteria is a null string, the search will be equivalent to a “select all”.
If the searchCriteria includes multiple search keys, the result is the intersection (AND function) of all the messages that match those keys.

searchCriteria = FLAGGED FROM "SMITH"

... returns all messages with \Flagged flag set AND sent by Smith.

You can use the OR or NOT operators as follows:

searchCriteria = OR SEEN FLAGGED

... returns all messages with \Seen flag set OR \Flagged flag set

searchCriteria = NOT SEEN

... returns all messages with \Seen flag not set.

searchCriteria = HEADER CONTENT-TYPE "MIXED" NOT HEADER CONTENT-TYPE "TEXT"...

... returns message whose content-type header contains “Mixed” and does not contain “string”.

searchCriteria = HEADER CONTENT-TYPE "E" NOT SUBJECT "o" NOT HEADER CONTENT-TYPE "MIXED"

... returns message whose content-type header contains “ e ” and whose Subject header does not contain “ o ” and whose content-type header is not “ Mixed ”.

As concerns the last two examples, notice that the result of the search is different when you remove the parentheses of the first search key list.

The searchCriteria may include the optional [CHARSET] specification. This consists of the "CHARSET" word followed by a registered [CHARSET] (US ASCII, ISO-8859). It indicates the charset of the searchCriteria string. Therefore, you must convert the searchCriteria string into the specified charset if you use the [CHARSET] specification (see the CONVERT FROM TEXT or Convert to string commands). By default, 4D encodes in Quotable Printable the searchCriteria string if it contains extended characters.

searchCriteria = CHARSET "ISO-8859" BODY "Help"

... means the search criteria uses the charset iso-8859 and the server will have to convert the search criteria before searching, if necessary.

Search value types

Search-keys may request the value to search for:

Search-keys with a date value: the date is a string that must be formatted as follows: date-day+"-"+date-month+"-"+date-year where date-day indicates the number of the day of the month (max. 2 characters), date-month indicates the name of the month (Jan/Feb/Mar/Apr/May/Jun/Jul/Aug/Sep/Oct/Dec) and date-year indicates the year (4 characters). Example: searchCriteria = SENTBEFORE 1-Feb-2020 (a date does not usually need to be quoted since it does not contain any special characters)
Search-keys with a string value: the string may contain any character and must be quoted. If the string does not contain any special characters, like the space character for instance, it does not need to be quoted. Quoting such strings will ensure that your string value will be correctly interpreted. Example: searchCriteria = FROM "SMITH" For all search keys that use strings, a message matches the key if the string is a substring of the field. Matching is not case-sensitive.
Search-keys with a field-name value: the field-name is the name of a header field. Example: searchCriteria = HEADER CONTENT-TYPE "MIXED"
Search-keys with a flag value: the flag may accept one or several keywords (including standard flags), separated by spaces. Example: searchCriteria = KEYWORD \Flagged \Draft
Search-keys with a message set value: Identifies a set of messages. For message sequence numbers, these are consecutive numbers from 1 to the total number of messages in the mailbox. A comma delimits individual numbers, a colon delimits between two numbers inclusive. Examples: 2,4:7,9,12:* is 2,4,5,6,7,9,12,13,14,15 for a mailbox with 15 messages. searchCriteria = 1:5 ANSWERED search in message selection from message sequence number 1 to 5 for messages which have the \Answered flag set. searchCriteria = 2,4 ANSWERED search in the message selection (message numbers 2 and 4) for messages which have the \Answered flag set.

Authorized search-keys

ALL: All messages in the mailbox.
ANSWERED: Messages with the \Answered flag set.
UNANSWERED: Messages that do not have the \Answered flag set.
DELETED: Messages with the \Deleted flag set.
UNDELETED: Messages that do not have the \Deleted flag set.
DRAFT: Messages with the \Draft flag set.
UNDRAFT: Messages that do not have the \Draft flag set.
FLAGGED: Messages with the \Flagged flag set.
UNFLAGGED: Messages that do not have the \Flagged flag set.

OLD: Messages that do not have the \Recent flag set.
SEEN: Messages that have the \Seen flag set.
UNSEEN: Messages that do not have the \Seen flag set.
NEW: Messages that have the \Recent flag set but not the \Seen flag. This is functionally equivalent to “(RECENT UNSEEN)”.
KEYWORD flag: Messages with the specified keyword set.
UNKEYWORD flag: Messages that do not have the specified keyword set.
BEFORE date: Messages whose internal date is earlier than the specified date.
ON date: Messages whose internal date is within the specified date.
SINCE date: Messages whose internal date is within or later than the specified date.
SENTBEFORE date: Messages whose Date header is earlier than the specified date.
SENTON date: Messages whose Date header is within the specified date.
SENTSINCE date: Messages whose Date header is within or later than the specified date.
TO string: Messages that contain the specified string in the TO header.
FROM string: Messages that contain the specified string in the FROM header.
CC string: Messages that contain the specified string in the CC header.
BCC string: Messages that contain the specified string in the BCC header.
SUBJECT string: Messages that contain the specified string in the Subject header.
BODY string: Messages that contain the specified string in the message body.
TEXT string: Messages that contain the specified string in the header or in the message body.
HEADER field-name string: Messages that have a header with the specified field-name and that contain the specified string in the field-body.
UID message-UID: Messages with unique identifiers corresponding to the specified unique identifier set.
LARGER n: Messages with a size larger than the specified number of bytes.
SMALLER n: Messages with a size smaller than the specified number of bytes.
NOT search-key: Messages that do not match the specified search key.

.selectBox()

.selectBox( name : string { , state : integer } ) : object

Parameter	Type		Description
name	string	→	Name of the mailbox
state	integer	→	Mailbox access status
Result	object	←	boxInfo object

Description

The .selectBox() function selects the name mailbox as the current mailbox. This function allows you to retrieve information about the mailbox.

To get the information from a mailbox without changing the current mailbox, use .getBoxInfo().

In the name parameter, pass the name of the mailbox to access. The name represents an unambiguous left-to-right hierarchy with levels separated by a specific delimiter character. The delimiter can be found with the .getDelimiter() function.

The optional state parameter defines the type of access to the mailbox. The possible values are:

Constant	Value	Comment
IMAP read only state	1	The selected mailbox is accessed with read only privileges. Messages with a "recent" flag (indicating new messages) remain unchanged.
IMAP read write state	0	The selected mailbox is accessed with read and write privileges. Messages are considered "seen" and lose the "recent" flag (indicating new messages). (Default value)

The function generates an error and returns Null if name designates a non-existing mailbox.

If there is no open connection, .selectBox() will open a connection.

If the connection has not been used since the designated connection delay (see 4D.IMAPTransporter.new), the .checkConnection() function is automatically called.

Returned object

The boxInfo object returned contains the following properties:

Property	Type	Description
name	string	Name of the mailbox
mailCount	number	Number of messages in the mailbox
mailRecent	number	Number of messages with the "recent" flag
