[Dovecot] Using plaintext auth and SSL

[Jeff Simmons]

I'm working with a company that presently has a Linux mailserver which all 
users have (no shell) accounts on. Mail is accessed via pop3 with plaintext 
authentication. They want to move to a system using imap with SSL. I'm 
building them a new server. I'd like to offer both for a while so we can work 
the bugs out and migrate users over to SSL imap over time. It appears that in 
order to limit the imap connections to SSL I will need to run two separate 
instances of Dovecot. Is this correct?
