That is very small. The simplest choice is to add the second and third domains to mydestination. The drawback of this is that all domains share one namespace; u...@example.com is the sane as u...@example.net is the same as u...@example.org. > I'm seeing conflicting info on setting this up.

Also look at the BASIC_CONFIGURATION_README, and then further through the VIRTUAL_README. -- http://rob0.nodns4.us/ Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
