Hi, I'm about to change a busy server (currently running under RedHat) to a debian server. I'm trying to figure out a way that will cause least mail delays to our customers whilst the dns records propagate (The IP's are going to change for the mail server).
The current server runs sendmail and the replacement is running postfix. What I would like to do at the changeover is to get sendmail to automatically relay any incoming mail over to the new machine based on it's IP and let the new machine handle distribution. Is there an easy way to do this with sendmail? Also, I haven't come up with an easy solution for pop mail. I'd be grateful for any ideas and feedback. -- Steve
