I was thinking of gregans.ie as a typical cobalt installation, i.e., it would have 2 A records for www.gregans.ie and gregans.ie
pointing at the same IP, and an MX record for gregans.ie, pointing at www.gregans.ie.

If that's the case, anyone sending an email uses the same information, and information leakage is not a problem.
