RE: [vox-tech] smtp question - blocked ip



Yes well, it's enough to prevent Pete from emailing out.  I like
DNSStuff.com, it's a great resource.

Spamhaus blocked Pacbell DSL ip addresses.  Evidently they felt that PacBell
has been ignoring there complaints regarding a few persistent spammers.  If I
thought I could get away with it here at work, I would probably block PacBell
DSL too.

I got 100,000 SPAM messages through my system at work over New Years Day from
a PacBell dsl ip address.

I average 150,000-200,000 a week from various open relays abroad, but the guy
screws up periodically and leaves enough info to trace him to a PacBell ip
address on occasion.  It changes so he's probably pppoe.  As we add reduncy
to entry points on our email system and expand the scope to the Enterprise, I
will prbably see a dramatic increase.  The sad part is, a lot of it is to non
existant email addresses.  SO not only is the spammer irratating me, he is
ripping off his customer.

<sigh>

They blacklisted Pac Bell?  Now there's a nice example of 
spitting into the wind.  :-)
