I have a mail server CentOS 64bit (4 Gb RAM) with Dovecot 1.2a4 and three accounts. I use Thunderbird 2.
If I enable SSL connection in Thunderbird 2, after three-five minutes I got a lot of different errors in Thunderbird (Server is not IMAP, Connection lost...).
Everything comes back to normal if I restart Dovecot in the server, but after 5 minutes I got the same errors.
This happens both with an ADSL connection (Thunderbird on Windows XP) AND with a direct 1 Gbit cross cable connection (Thunderbird on Ubuntu 64 8.10).
If I disable SSL connection on Thunderbird, everything comes back to normal and I don't get any error.
The SSL-related options in dovecot.conf are:
ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem ssl_parameters_regenerate = 47 verbose_ssl = yes ssl_cipher_list = ALL:!LOW disable_plaintext_auth = no
What kind of logging can I enable to trace this error?
On the logfile I find something like taht (there are only 3 seconds between the first and the last line)
