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
mail...@example.com              mailman
mailman-ad...@example.com        mailman-admin
mailman-boun...@example.com      mailman-bounces
mailman-conf...@example.com      mailman-confirm
mailman-j...@example.com         mailman-join
mailman-le...@example.com        mailman-leave
mailman-ow...@example.com        mailman-owner
mailman-requ...@example.com      mailman-request
mailman-subscr...@example.com    mailman-subscribe
mailman-unsubscr...@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-ow...@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 ?

mail...@subdomain.example.com              mailman
mailman-ad...@subdomain.example.com        mailman-admin
mailman-boun...@subdomain.example.com      mailman-bounces
mailman-conf...@subdomain.example.com      mailman-confirm
mailman-j...@subdomain.example.com         mailman-join
mailman-le...@subdomain.example.com        mailman-leave
mailman-ow...@subdomain.example.com        mailman-owner
mailman-requ...@subdomain.example.com      mailman-request
mailman-subscr...@subdomain.example.com    mailman-subscribe
mailman-unsubscr...@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-boun...@subdomain.example.com
To: mailman-ow...@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
