I'm experienced with moving databases and site content to minimize downtime and non-synchronized data while DNS changes propagate through every network.... however, email is a different story.

Does anyone know if there is a quick and easy way to route ALL email to the new server even if the emails being sent to our domain were routed to our old server?

In the past when we would move it would take about 1-2 months before all traffic was going to our new server - during which time I would access email accounts on both servers. However, now we have a few people accessing multiple accounts. I'm just curious if there is something we can do with sendmail on our current server to make it forward emails to the new server.

If there isn't a quick solution I guess I could set up an alias or virtmap for each user. Which is preferable in this case...alias or virtmap?

My second question is about moving the mail from the old server to the new. I’m on a FreeBSD system (4.4) and want to make sure I get ALL the mail moved over – do I just need to move the “.mailrc” file over for each user?

I appreciate any advice you may have!

Make sure the nameservers the old server resolve off reflect an updated MX entry (sending mail to the new machine).

Also make sure that old server knows the mail is not to be delivered locally. This part will depend on the OS and version. Usually the file is called local_hosts or similar.

marcs,

Thank you for your reply...I hate to ask, but could you elaborate a little bit? I don't do much with sendmail beyond adding/removing accounts.
