Okay. The only notable difference between sending directly to an address
and using the "mailing list" feature (in OpenGroupware.org) is this
header:

Normal send:
Return-Path: <[user]@mainstreamliving-dsm.org>

Using bulk mail (mailing list feature):
Return-Path: <[a system account]@teamcsa.org>

Would this look like relaying to the destination server?
Looks like this may be my issue.
