RE: [cobalt-users] MX problem ?

[Clive Harper <CHarper@xxxxxxxxxxxx>]

No, the IP for mail.domain.com can be the same IP as www.domain.com and
domain.com, it is normal for the same IP to handle both web and mail
services
for a domain.

e.g.

A - domain.com - 192.168.100.1
A - www.domain.com - 192.168.100.1 with automatic reverse generation on
A - mail.domain.com - 192.168.100.1
MX - domain.com - mail.domain.com - high priority

Any mail sent to user@xxxxxxxxxx would be handled by mail.domain.com
which resolves to 192.168.100.1

as long as you have the minimum DNS entries as described above then
your DNS should be configured fine for web and mail services.
