Presumably, that reference is to
<http://www.mail-archive.com/mailman-users%40python.org/msg62067.html>.
If you are going to refer to an archived message, please give a complete
URL.

And all look OK.

The transport to Mailman still requires aliases. See below. As to why
(if) the transport_maps are not effective, I'd like to see the actual
Postfix log messages, not just the DSN.

Your transport maps will just map the list addresses to the local
transport. You still need aliases to get to Mailman. The above line
needs to include hash:/var/lib/mailman/data/aliases, i.e.

alias_maps = hash:/etc/aliases hash:/var/lib/mailman/data/aliases

I have updated the FAQ at <http://wiki.list.org/x/10715238> to hopefully
make this more clear.

And presumably mydom.ain is one of the virtual_mailbox_domains. I don't
know off hand whether or not the specific address appearing in
transport_maps takes precedence over the domain in
virtual_mailbox_domains. I think it should, but ...

Add the aliases to alias_maps and if you still have the problem, post
the Postfix log messages.

These all look OK.
