[Mailman-Users] not your father's MX loop

[Jaz-Michael King]

Hi, here's my problem, I hope someone has experienced the 
same or similar. I've combed through the archives and found 
nothing.

Mailman is supposed to deliver to listmember at domain.com 

For some reason, mailman adds my domain, so the delivery 
is attempted for listmember at domain.com.mydomain.us 

Which, of course, gives me a loop error.

Here's a snip, email user names munged:
