This gets complicated. My question at this point is how is mail to
listname at example.com getting to Mailman. Any virtual mappings in
Mailman's virtual-mailman will be for the listname at myhost.example.com,
etc. addresses, so Postfix can't be relying on that for delivery. So
if example.com is not a local domain, how is mail to that domain
getting to Postfix's local delivery in order that Mailman's pipe
aliases are effective. Are transport maps involved for this domain?

I probably need to see "postconf -n" and to understand whether there
are only list addresses @example.com or if there are non-list virtual
mailbox users @example.com too.

Also, there are mailman generated addresses such as list-bounces, and
these are currently all generated @myhost.example.com, so how is that
mail delivered?
