[Mailman-Users] Question regarding implementation, hostname vs. domainname

[Albert Whale]

I host a variety of Mailmain lists for Non-Profit organizations.  One is
for the Local Boy Scouts, the mailing list address is listed
test at abs-comptech.com (not the real mailing list, but similarly configured).

However posting to test at abs-comptech.com (the virtual name of the
machine) does not work, but posting to the name of
test at ns4.abs-comptech.com does work.

What can I do to have the list test at abs-comptech.com respond like
test at ns4.abs-comptech.com?
