yes, Imail doc is simply wrong about putting mail.domain.com into Imail or into DNS. >What are the best steps to make a change? In Imail, remove mail.domain.com, and use domain.com as the single default hostname. >1. Request DNS MX record change from mail.domain.com to domain.com. in DNS: ;the MX hostname doesn't have to be the same as the domain.com name: domain.com. mx 10 mx1.something.com. domain.com. mx 20 mx2.whatever.com. smtp.domain.com. A ip.ad.re.ss ; clients send outbound here pop.domain.com. A ip.ad.re.ss imap.domain.com. A ip.ad.re.ss webmail.domain.com. A ip.ad.re.ss All the ip's above are the Imail ip's initially. Then when you add IMGate, you simply change the ip of smtp.domain.com from ip of imail to ip of imgate. The users don't have to change or know anything. If they were running SMTP AUTH with Imail, no problem because IMGate won't announce AUTH, so the mail client programs "should" not attempt it. They will relay mail to smtp.domain.com and it will go through.
