[Mailman-Users] 2 domain, mailman and postfix

[mc2575 at mclink.it]

I have a linux serevr with 2 domain name redirect at the same ip address.

I run Mailman + postfix in one of the domain.

I can use the same mailman + postfix to create a mailing list in the other
domain?
I have read the "man 5 virtual" but I have not understood much.

 Is a How To available for my problem?

Thanks advancely
