[Mailman-Users] Error unknown virtual host mailman

[Gines Granados Bayona]

Hello everyone, I'm new in mailman and just made an installation of zero
mailman, with potsfix on centos 6. I have an error when trying to create a
new list in which shows me:
Error: Unknown virtual host... *** *** *** ***
I do not know what parameter settings I could make wrong, or should change
and though I've read several forums, I see that the fix are settings are
different , do We can indicate that parameter must change?

Greetings and thank you
