Thanks for your answer, I use 1 frontend because it's a test lab. Cyradm was
just an example tool.
My main question was "How to troubleshoot IMAP connection to backend". I am
unable to make a SELECT with imtest or any IMAP client.
See below the results with imtest.
S: L01 OK User logged in
Security strength factor: 0
a SELECT INBOX
a NO Server(s) unavailable to complete operation
b SELECT user.user1.INBOX
b NO Server(s) unavailable to complete operation
and the log
Mar 23 09:50:44 proxy1 cyrus/proxyd: connect(imapback.rescom.mi) failed:
Why there is no communication when connecting to IMAP ?
What does mean "connect(default) failed: Invalid argument" in the log ?
