I have used an IMAP activity with the following parameters
- MailFolder “Posteingang” / “Inbox”
- Port 993
- SecureConnection “StartTlsWhenAvailable”
to connect to an IMAP mail account. It tries for approximately 40 seconds and the returns the error code “The IMAP Server has unexpectedly disconnected” (Exception Type: ImapProtocolException).
When I use the same settings on the same PC with a thunderbird mail client it works fine and all mails could be read… and Telnet connection to the server / port is also ok.
Unfortunately my collegues from the mailing Team have no clue what is the cause.
Any help appreciated,
