I would not be at all surprised if the fault is a misconfigured MTA 
which is inappropriately replacing the external domain name with the 
internal domain name, for e-mail addressed to external clients.

Since there is this schizophrenia with regards to the domain names 
used, I'd recommend keeping all that completely outside of Mailman. 
Only worry about one given set of internal domain names for everyone, 
then let the MTAs to the outside world be responsible for handling 
all internal/external domain name conversion in both directions. 
You'd probably have to fix up the web server system in the same way.

The other alternative is to logically put the Mailman server in the 
external network and have it know nothing about the internal users, 
and then let the MTAs and web proxy servers handle the translation 
the other way.

e-mail account for me at this domain, please make sure you correct that
with the current address.
