Thank you for your help. But I want all user in backup.example.com has
same domain. Let me explain bit more.
I have domain abc.com with topology below:
Incoming Email: Internet -> MX Filtering for abc.com -> Real Mail
Server with Webmail
Outgoing Email: Client include Webmail -> MX Filtering for abc.com
and relay -> Internet
Now, We have other Real Mail Server with Webmail2 in other place, so
the topology now:
Real Mail Server with Webmail2
/
Incoming Email: Internet -> MX Filtering for abc.com /-- Real Mail
Server with Webmail
And we make sync for everyday between webmail and webmail2. Also, I
have make sync for user between webmail and webmail2. We are using
postfix, amavis, clamav, and spamassassin
Thank you
