Quoting Zalezny Niezalezny <zalezny.niezale...@gmail.com>:
I dont want to route any E-mails. I simply would like to stop old server,
tar everything in the proper way and migrate on the new host. This is my
target.
Then just block all incoming traffic on port 25 and 587 (or whatever
your users are using).
After everything has been processed and the Que is empty, tar compress
everything and move it to the new server.
Once that is done, change the MX entries to point to the new server
and you are done.
No mails will be lost in the meantime.
If you additionally change the TTL of the according Zone entries of
your domain to something very small (5 min), the propagation of the
new entries will be faster.
Regards,
Michael
