Is DH doing this to other long time DH customers? Of course everything email is broken on a Monday morning. This is only the second such move of my account in as many months. The first one was just about as f'd up.
6 AM EST I get the following:
This message is to let you know that we are moving your mail service and mailboxes to a new server. We apologize for the lack of notice, but this move was necessary to insure stability and increase the performance of your mail service.
What does this mean to you? Hopefully nothing! PLEASE READ THIS FULL MESSAGE though, as it may help you fix any problems that come up as a result of the move. These are the most common problems that we're seeing after accounts have been moved.
If you are hosting your DNS outside of DreamHost, or have your mail being processed by an outside spam filtering service, you will need to update your DNS records to point to the new server. If you don't do this, your mail will attempt to be delivered to your old mail server and delivery will fail. You can see what your new mail MX records are by going to the 'Mail'->'Custom MX' section of your web panel and clicking 'edit' for the domain in question.
You will see your new MX record at the bottom of the next page. Just update that where you're hosting your DNS or with your mail filtering service and you will be all set.
FILTERING (Advanced Users)
If you had custom forwarding/filtering set up via a .procmail (filtering) or .forward (forwarding) file, or you read your mail through a program like Pine or Mutt, you will need to make some changes for that to continue to work correctly. Your mailbox is no longer tied to your shell/ftp user, so it will no longer be processed by those files in your users home directory. You will need to visit the 'Mail'->'Message Filters' section of the web panel to configure your filters now. You can either set up all your filters via that interface, or if you need more control over your filters you can set all mail for a given address to forward to a shell account. If you choose the latter, we have more specific details on how to set that up here:
That's it really.. and again, we really apologize for the abrupt nature of this move!
