I recently upgraded to 12.04, and haven't been able to get dovecot working. I'm posting here because the dovecot package I got differs from what it talks about on the dovecot wiki, notable the nonexistence of the doc directory.
The problem appears to be one of authentication. Here is a sample from the logfile:
I tried using the certificate from my old installation, and then downloaded the mkcert.sh script from the dovecot site and rebuilt the cert (I also downloaded the config file for the script and edited it). I've built certs before, I hope I got that right.
dovecot: imap-login: Disconnected (no auth attempts): rip=184.108.40.206, lip=220.127.116.11, TLS handshaking: SSL_accept() failed: error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate: SSL alert number 42
When I start thunderbird, I also get one of those ephemeral messages that says it could not connect to my mail server - and I don't start thunderbird until I have issued a restart command for dovecot.
I'm wondering if this is related to PAM? I really don't know anything about PAM, so I tried to follow all the directions, but I remain nervous about it.
Thanks for any help.
