This says nothing about the DNS records for your server. It only says
you can access DNS records for the internet names you try to access.
It doesn't say that I can find proper DNS records to allow me to
access you or send mail to you.

What doesn't work?

Can you access Mailman's web interface?

Do post's bounce? If so, why? If not, do they reach Mailman's archives?
Are they logged in Mailman's post log and smtp log. Is there anything
in Mailman's smtp-failure log?
