[Mailman-Users] multiple domains - mailman-bounces at subdomain.example.com not

[Konrad Wawryn]

Hi,

maybe some one will be able to support me here.

In our Mailman configuration we are using two sender domains:

example.com
subdomain.example.com


In the file /etc/mailman/virtual-mailman    I have found only this 
addresses

# STANZA START: mailman
# CREATED: Thu Jun 22 10:43:16 2017
mailman at example.com              mailman
mailman-admin at example.com        mailman-admin
mailman-bounces at example.com      mailman-bounces
mailman-confirm at example.com      mailman-confirm
mailman-join at example.com         mailman-join
mailman-leave at example.com        mailman-leave
mailman-owner at example.com        mailman-owner
mailman-request at example.com      mailman-request
mailman-subscribe at example.com    mailman-subscribe
mailman-unsubscribe at example.com  mailman-unsubscribe



but there are no entries for subdomain.example.com.


When system sending messages with sender domain - subdomain.example.com 
out - then we have a problem with e-mail loop because e-mail address

mailman-owner at subdomain.example.com is not known for the mailman and 
server pushing it to the relay.


I would like to understand how its working with multiple domains. Does 
mailman and mailman-*@* addresses are reserverd only for root domain ? 
What about subdomain ?

Do I have to create separate entry like this one to resolve my e-mail 
loop issue ?

mailman at subdomain.example.com              mailman
mailman-admin at subdomain.example.com        mailman-admin
mailman-bounces at subdomain.example.com      mailman-bounces
mailman-confirm at subdomain.example.com      mailman-confirm
mailman-join at subdomain.example.com         mailman-join
mailman-leave at subdomain.example.com        mailman-leave
mailman-owner at subdomain.example.com        mailman-owner
mailman-request at subdomain.example.com      mailman-request
mailman-subscribe at subdomain.example.com    mailman-subscribe
mailman-unsubscribe at subdomain.example.com  mailman-unsubscribe



In the postfix mail_log I see that instead of to deliver this message to 
local mailman accounts

 From: mailman-bounces at subdomain.example.com
To: mailman-owner at subdomain.example.com


postfix is forwarding that messages to the next relay.

Do I need to configure for all sender subdomains aliases where each 
alias will point default account mailman, mailman-*@example.com  or each 
subdomain should use its own aliases mailman, 
mailman-*@subdomain.example.com ?



Thanks in advance for Your support.


Cheers
Konrad
