Re: denial of service on ISN list

Bummer, ISP' not wishing to take responsibility for their spamming
clients, almost as bad as those ISP' that let compromised systems ride
their backbones while spewing attacks at the rest of the internet.  You'd
be better served to find an ISP that knowns how to play better with t;s
internet neighbors then whining here.

Thanks,

Ron DuFresne

I can't subscribe to ISN because their mail server thinks my mail

ISPs in the UK, and that this server might be used by hundreds of
thousands of people.

I put it to ISN that your system allows people to be kicked off the
list.  All I need to do is fake some spam from my enemy's SMTP to the
list, and you block the entire server.  When another of Pipex'
100,000 subscribers attempts to join, they are blocked too.  Not
good.

OK, so you're a Ph.D.  Just don't touch anything.
