Hmm... if you are using some kind of unix, try testing from an
outside DNS server (try 206.136.25.12) with something like this:
> set q=ptr
(sets the questions to test the 'ptr' (reverse) record)
>123.123.123.123
(the IP of one of your PM's IPs)
if this works, then its a problem with slow reaction of the DNS
server on the IRC server site (something I have found many times),
Also, if you set the DNS server in your portmaster, you should be
getting DOMAIN NAMES, not IPs when you do 'sh ses', etc etc.
