Dan: Thanks for the review of the move planned & according to your check
list, it does indeed look like I have all of the bases covered. ALL of the
directory structures/permissons are eXactly identical on both servers.

I can personally administer the MX records and always save that for last
after a server is configured. The only sloppy part will be the propagation
of the change in IP addresses, especially since the zsubscriberz are in
more than 180 countries. This means, for at least a few hours (or even
days), some DNS global servers around the globe will still be seeing the
old IP address for the domains with the lists being moved. That will
persist until those servers flush their respective caches of course. Some
zsubscriberz may have some trouble with the turnaround until the new IP can
resolve.

So, the only 1 of your 3 gotchas that is a little uncontrollable is #2, the
MX records which I will change immediately after moving the directories,
changing virtusertable, and, oh yes..., plus the /etc/mail/local-host-names
file must have the new mail.domains added which also tells the new server
which hosts are to receive the mails. 

Then, I must run: /usr/sbin/makemap hash virtusertable.db < virtusertable
for the new domains. Finally, restart sendmail.

Guess, then we've covered averything.

The main concerns was the part about just copying the directories/files
from OLD server to NEW.... your answer concludes that yes I can.... if they
are identical in every way.

Thanks, Dan....!!
