[Mailman-Users] can a single mailman/postfix instance run lists for two different domains?

[Jack Beanstallk]

Hi,

We have a mailman list running:-

mailman hostname = lists.example1.org
mailling list domain = example1.org

mx record for example1.org points to lists.example1.org

Mailman and postfix are configured to use the hostname and
domain explicitly to handle example1.org mailing lists.

Can a single mailman/postfix instance be configured to handle mailing lists
for two different domains, if yes, how is this configured?

e.g.

mailman hostname = lists.example1.org

mailling list domains to handle
example1.org
different1.org

mx record for example1.org points to lists.example1.org
There is no mx record for different1.org but if mailman/postfix can handle
multiple domains, the mx record can change to point to lists.example1.org

Any help will be greatly appreciated.

Thanks
