Hello 
we try to integrate eM Client in our mail-system. Unfortunately we encounter repeating sync problems with our dovecot-imap-server. On a regular basis, the following input is in the log at eM Client:
11:30:24 [email protected] [IMAP] MailClient.Accounts.ConnectionException: Die Synchronisation des Ordners’[email protected]/Posteingang’ ist fehlgeschlagen mit folgendem Fehler: Der Server hat nicht innerhalb von 00:01:00 geantwortet
—> System.TimeoutException: Der Server hat nicht innerhalb von 00:01:00 geantwortet

In the dovecot log there is the following input:
May 21 11:36:18 ucs dovecot: imap([email protected])<29847><NRf9iPMYzf/AqGR9>: Connection closed (UID FETCH running for 0.041 + waiting input for 61.811 secs, 0.001 in locks, 23 B in + 87373 B out, state=wait-sync) in=5132 out=92339 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=1 body_bytes=87329
I tried to figure out what’s wrong or what could be a hint. The only thing I recognized is that the body_bytes is always the same amount of bytes.
Please give me a hint where I am able to find a solution for that.
Best regards.
