I'd like to host multiple domains though a central dovecot proxy - however, I need to present different certs to different hostnames (which are on different IPs).
I can't see a way to this in the documentation, is it possible?
You can't do this with a single instance, but you can run parallel instances of dovecot on the same machine. Create a second dovecot_mumble.conf with the alternate config and start the second instance with -c /path/to/dovecot_mumble.conf. Each instance needs its own .conf (they can share sql/ldap config files), base_dir and auth sections.
I run multi-instance setups in production--it makes it possible to take down the imap service without breaking postfix since postfix smtpd will have fatal startup errors unless dovecot is running.
