I'm using postfix-to-mailman script.

<rant_warning> postfix_to_mailman.py is user contributed software which is 'officially' not supported by the GNU Mailman project. Why are you using it? If you are using it because that's the way your Debian/Ubuntu/other package installed Mailman, you should be talking to Debian/Ubuntu/other.

Also, there are Postfix lists for Postfix support. See <http://www.postfix.org/lists.html>. </rant_warning>

And I have my domain in 'add_virtualhost' variable (in the mm_cfg.py file).

This is not going to make any difference to Postfix/postfix_to_mailman.py.

I've noticed now that there is a 'virtual-mailman' file at
/etc/mailman, but I think it's useless because I'm using
postfix-to-mailman.

Whether or not it's used depends on what you've put in Postfix's main.cf.

My best guess in the dark here is you have MTA='Postfix' in mm_cfg.py so Mailman is generating list aliases in it's data/aliases file and you are referencing that file in alias_maps in Postfix main.cf. And, delivery from local senders is working because it is using these aliases, not postfix_to_mailman.py.

Then, something is not configured correctly for postfix_to_mailman so it isn't working, and that's why mail from outside to your (virtual) lists domain isn't working.

See the documentation at the beginning of the postfix_to_mailman.py script on how to configure Postfix, or do as Andrew suggests in his reply and set up the recommended Mailman/Postfix integration and don't use postfix_to_mailman.py.

And if you wan't further help here or from postfix lists, post the output from postconf -n and your master.cf changes.
