Hi,
I have an fc18 system with postfix and dovecot-2.1.13 and have configured them to use sasl for SMTP Auth and Maildir with imaps.
The system is running now, so I'm trying to set up thunderbird to autodetect all settings during the initial account setup. However, it seems to want to use port 143 and STARTTLS, and not port 993, which is what I would expect. When I force it to use 993, I receive a certificate failure message:
Mar 12 23:20:45 propnew postfix/submission/smtpd[14423]: initializing the server-side TLS engine Mar 12 23:20:45 propnew postfix/tlsmgr[14425]: open smtpd TLS cache btree:/var/lib/postfix/smtpd_tls_session_cache Mar 12 23:20:45 propnew postfix/tlsmgr[14425]: tlsmgr_cache_run_event: start TLS smtpd session cache cleanup Mar 12 23:20:45 propnew postfix/submission/smtpd[14423]: connect from unknown[192.168.1.43] Mar 12 23:20:45 propnew dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=192.168.1.43, lip=66.111.222.101, TLS: SSL_read() failed: error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate: SSL alert number 42, session=<BGBS5MXXhQDAqAEr>
After doing a bit more research, it looks like it's failing because Thunderbird doesn't prompt to accept the self-signed certificate during the "auto config" part of the setup, so just falls back to using port 143.
Although I think it's still using TLS on 143.
I'm really hoping someone can help me to clarify more specifically what's going on here.
Thanks, Alex
