Domain name: example.com IPA Server: ds01.example.com Dovecot Server: mail01.example.com IPA Client: workstation01.example.com IPA User: user1 and user2
Please Note: This guide describes using SSL combined with Dovecot to deliver IMAPS support. This guide is not designed to cover how to create a valid SSL vertificate.
