[Mailman-Users] Site not responding

I am at work, and unable to ssh to or access the webmin for my site, running on http://fyrenice.com/mailman/

I am confused why the site doesn't seem to be responding, i.e., it won't reflect back out if I email to <listname>@fyrenice.com with 'help' in the subject or body. Isn't that supposed to trigger the list to reply back with instructions, with help information on a specific site?

At work here I am behind a corporate firewall, so I can't navigate and connect via http://fyrenice.com/mailman/admin. Strangely enough though I can connect to the webmin using http://fyrenice.com:<portnumber>/ and I can log in to my router.

Could someone help me understand this behavior?

Thank You,

Scott
