OK

It appears that the issue is probably that Postfix is not delivering
the mail to Mailman. If this is not the case, see the FAQ at
<http://wiki.list.org/x/A4E9> for other ideas.



>I'm thinking that if everything else is working as it should, it is possible to be a "http://localhost/mailman/admin/modulos/" configuration problem, the GUI configuration.


The GUI per se has nothing to do with the flow of mail through Mailman.

>In short, I have to add a "MTA='Postfix'" to the mm_cfg.py file. and then make a refernce to the mailman aliases file in the "virtual_alias_maps=hash:/etc/mailman/aliases"    tag, I guess that worked for me the first time. (I have a bad memory).


When you changed the domain name, did you update mm_cfg.py and run
fix_url per the FAQ at <http://wiki.list.org/x/gIA9>, and then run
Mailman's bin/genaliases to rebuild the Postfix aliases?

In RedHat/Centos packages, /etc/mailman/aliases is a symlink to
Mailman's data/aliases, and this is an alias_map file, not a
virtual_alias_map file.

At this point add

VIRTUAL_HOSTS.clear()

It's not critical, but it removes the 'wrong' entry from Defaults.py

Irrelevant because it's all comments.

Again, this file is an alias_maps file, not a virtual_alias_maps file.
