In case it is useful, when the authentication fails I get this in /var/log/auth.log: ------------------------------------------------------------------ May 24 15:31:38 server2 saslauthd[2701]: do_auth : auth failure: [user=daniel] [service=imap] [realm=] [mech=sasldb] [reason=Unknown] ------------------------------------------------------------------ It seems that authentication is done through IMAP and I have previously installed the Cyrus packages. Thanks in advance, Kind regards, Daniel
