BTW Bob, I answered your question on July 18 when you asked it the first time.

The setup of GNU Mailman with the lists subdomain in $mydestination (and *without* the transport_maps!) is trivially easy. Yes, you add the Mailman aliases file to alias_maps. There is no need to maintain parallel virtual_alias_maps entries nor the "mailman" transport. It all Just Works, out of the box. > On 2016-07-25 05:14 PM, Viktor Dukhovni wrote: > >On Mon, Jul 25, 2016 at 05:04:15PM -0600, Bob wrote: > > > >>>>lists.faithwalk.ca mailman: > >>>>faithwalk.ca mailman: > >>>There's your mistake, you can't deliver non-list mail via > >>>mailman, it only handles mailing lists.

The "other issues" might be namespace collisions. If you host more than one list domain, you can only have any particular list name in one of them. For example, if you host lists.example.com and also lists.example.org, and you have "listn...@lists.example.com" as a Mailman list, you can't also have "listn...@lists.example.org". And yet, those addresses would be seen as valid for smtpd recipient validation, so you might need to put in check_recipient_access restrictions to prevent getting list mail for the wrong domain. Similarly, if your regular users are using local(8) delivery, you should consider whether you have other namespace collisions in regular users with Mailman lists (and vice versa.) If you have a system user named "info" and a Mailman list called "i...@lists.example.com", the system user "info" won't get any mail; it would go to the Mailman list alias. Perhaps neither of these are problems for you; if so, don't worry about it. If namespace collisions are a problem, see: http://www.postfix.org/VIRTUAL_README.html#virtual_alias http://www.postfix.org/ADDRESS_CLASS_README.html#virtual_alias_class -- http://rob0.nodns4.us/ Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
