IMAP_Login


IMAP_Login ( hostName ; userName ; password ; imap_ID {; sessionParam} ) -> Function result

Parameter	Type	Description
hostName	String	Host Name or IP address of the IMAP server
userName	String	User name
password	String	Password
imap_ID	Longint	Reference to this IMAP login
sessionParam	Longint	1 = Use SSL, 0 or omitted = Do not use SSL
Function result	Integer	Error code

Description

The IMAP_Login command logs the user onto the IMAP electronic mail server with the given user name and password.

This particular login is given a connection reference (imap_ID) to which subsequent IMAP commands can refer.

The connection is closed using the IMAP_Logout command or when the IMAP server inactivity timer has timed out.

hostName is the host name or IP address of the IMAP electronic mail server. It is recommended that the host name be used but, if needed, an IP address may be used.

userName is the user's name on the IMAP electronic mail server. The userName should not contain the domain. For example, for the address “jack@4d.com”, the userName would be just “jack”.

password is the password for the userName on the IMAP electronic mail server.

imap_ID is a long integer variable into which a reference to the connection just established is returned. This parameter must be passed a 4D variable in order to accept the returned results. The variable will be used in all subsequent commands which perform actions related to this session. If IMAP_Login fails, imap_ID is set to zero.

The optional sessionParam parameter enables the SSL protocol for a connection:

If you pass 1, the connection to the IMAP server will be made in SSL (synchronous mode),
If you pass 0 or omit this parameter, the connection will be made in standard, non-secure mode.

Example

Here is a typical connection sequence:

 $ErrorNum:=IMAP_Login(vHost;vUserName;vUserPassword;vImap_ID;1)

 If($ErrorNum =0)

    C_TEXT(vCapability)

    $ErrorNum:=IMAP_Capability(vImap_ID;vCapability))

  ` IMAP commands using vImap_ID parameter

 End if

 $ErrorNum:=IMAP_Logout(vImap_ID)
