[Mailman-Users] Testing, checking

[Jones, Scott (GE Money, consultant)]

Is there a checklist of things to look over, once Mailman is installed,
to make sure the site becomes visible to the internet? 

My site, http://fyrenice.com/mailman works when I am at home on my LAN,
but I can't access it when not at home, i.e., it's not yet working
correctly. I have these ports opened: 22, 25, 80, 110, 443 via my
router. What other ports should I consider? 

Please advise!

Scott
