[cobalt-users] RaQ2/3: All email on one server

[BlackSun <admin@xxxxxxxxxxx>]

What's the best way to configure all of my virtual sites (spread
out over several RaQ2s, RaQ3s and RaQ3is) so that the email can
be handled by a single server (preferably a spare RaQ2)?

Do I simply change the MX records on my primary DNS server to
read from:

  clientdomain.com
  mail.clientdomain.com

to:

  clientdomain.com
  mail.server.com     -or-

  clientdomain.com
  mail.mydomain.com
   (with an A record pointing mail.mydomain.com to either
   the server or mail.mydomain.com)

Thanks for any assistance.
