Upload / append an email to an IMAP mailbox and get the UID of the appended email. Visual FoxPro

lnSuccess = 0

* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loImap = CreateObject('Chilkat.Imap')

* Connect to an IMAP server.
* Use TLS
loImap.Ssl = 1
loImap.Port = 993
lnSuccess = loImap.Connect("imap.example.com")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Login
lnSuccess = loImap.Login("myLogin","myPassword")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Check the capabilities of the IMAP server.
lcCap = loImap.Capability()
? "IMAP capabilities: " + lcCap

* If the capabilities string contains the substring "UIDPLUS", then 
* the UID of the appended email will be available in the AppendUid property (see below).

* For example, the GMail IMAP server has these capabilities (at this current time)
* * CAPABILITY IMAP4rev1 UNSELECT IDLE NAMESPACE QUOTA ID XLIST CHILDREN 
* X-GM-EXT-1 UIDPLUS COMPRESS=DEFLATE ENABLE MOVE CONDSTORE ESEARCH UTF8=ACCEPT 
* APPENDLIMIT=35882577 LIST-EXTENDED LIST-STATUS

loEmail = CreateObject('Chilkat.Email')

* Load the email from a .eml file.
lnSuccess = loEmail.LoadEml("myEmail.eml")
IF (lnSuccess <> 1) THEN
    ? loEmail.LastErrorText
    RELEASE loImap
    RELEASE loEmail
    CANCEL
ENDIF

lnSuccess = loImap.AppendMail("Inbox",loEmail)
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    RELEASE loEmail
    CANCEL
ENDIF

* If the IMAP server supports the UIDPLUS extension, then the 
* imap.AppendUid will contain the UID of the appended email.
* Otherwise AppendUid will be 0.
? "UID of appended email: " + STR(loImap.AppendUid)

* If the IMAP server does NOT have UIDPLUS, then a program can 
* first select the mailbox, get the value of the UidNext property,
* and then append.  The appended email SHOULD have a UID equal to 
* the UidNext that was obtained just prior to appending (assuming no other
* program is simultaneously appending an email to the same mailbox).

* Note: It is not required to select a mailbox to append.  The select is only
* done for the purpose of obtaining the UIDNEXT value.
