Mail Routing to domain and sub-domain

Mon Oct 13 14:36:25 PDT 2003

test.pdi.com does not exist on your public nameservers
likewise aleph.test.pdi.com. does not exist.

I suspect your problem is actually that your mailserver is stripping it
off though , in a masquerade-for-every-machine-in-domian.

Publish  test.pdi.com publically, then try from an outside server
