[Dovecot] Looking for HOWTO for fc18 with postfix/TLS/imaps

Hi all,

Does there already exist a document that outlines the best approach to implement postfix with dovecot? I'd like to set up a Maildir system with TLS clients and SMTP Auth. I don't think I need to require client certs, but want to avoid cleartext passwords.

It's unclear to me whether to use 143 with TLS or 993. I've currently set it up using 143 with STARTTLS using normal passwords. Is this correct?

Can I use a regular apache web cert to provide an authorized cert and key to use for authentication by the clients?

Thanks, Alex
