A CGate mail server can handle both multiple domains and domain aliases for
each separate domain.

If you want a user's email to show 'name@domain.com', you must specify the
domain as that name, and then in the domain settings, specify the alias of
mail.domain.com. Configure the domain to 'be' at the IP address assigned to
mail.domain.com, and all should be well.

Then in the DNS, only the 'mail.domain.com' must point to the IP address of
the machine hosting CGate with that domain. the root 'domain.com' does not
need to point to that machine at all. For CGate Webmail, you can have a link
on your 'domain.com' and 'www.domain.com' main pages that link to
'mail.domain.com', and anyone wishing to access webmail can hit that link
and be presented with the webmail login interface. Be sure you specify your
listeners for the right IP addresses and ports.

We use QuickDNS Pro and CommuniGate Pro together in such a fashion, and it
works great. If anyone needs specific assistance with making the two work
together, I'd be happy to help.
