Hello,
I just decided to try dovecot again after a long pause, and I must say that I am very impressed with the speed and resource usage, even when running with UNIX mailboxes.
However, I have a problem with SSL. Every two minutes the connection is frozen, and the client has to reconnect after it times out waiting for a response from the server.
My IMAP client fetches all headers, and then caches all messages in my mailboxes. However, if I do this while connected to dovecot using SSL (imaps, port 993) the connection times out roughly every two minutes, and the IMAP client must close the connection, reconnect and resume operations from where it left off. This makes resynching a 40000 message 300MB folder take VERY long :-)
Using the same client, connected to the same server and syncing the same mailbox connecting to regular imap port (no TLS, port 143), everything works smoothly.
The very same client, server and mailbox works flawlessly with uw-imapd and SSL.
I have turned on rawlog, and everything seems to be OK. I am unable to dump the wire, because it's SSL, so not sure what to do to debug this.
One thing I find a bit strange is that /var/run/dovecot/ssl-parameters.dat is a 0 byte file. Is this normal?
Client: Apple Mail 1.3.11 (v622) Server: dovecot 0.99.14, installed from ports on FreeBSD 5 dovecot.conf:
