After I replaced my certificate with a new one yesterday, I'm seeing some ssl related errors. [...] dovecot: imap-login: Disconnected (no auth attempts in 1 secs): [...] dovecot: imap-login: Disconnected (no auth attempts in 0 secs): [...]
These log messages indicate that it was the client who stopped doing the full login procedure. My first guess would be that a majority of those clients want their user/admin to confirm trust in the new server cert before they "leak" authentication tokens (user+auth) to it.

Separate subject, but couldn't help but notice, SSL3 is being used?
SSLv3 and at least the earlier versions of TLS share a lot of underlying cryptalgorithms, so the log messages (from double-used code) still *say* "SSL3". (If you want to be *sure*, run a scanner like sslyze against the server.)
