Providers removing blocks on port 135?

Hi, NANOGers.

] I still disagree with this.  To prevent SPAM, people shouldn't run open
] relays and the open relay problem should be solved.  Breaking legitimate
] port 25 traffic is a temporary hack.

I suspect that most spam avoids open relays.  The abuse of
proxies, routers, and bots for this purpose is far more in
vogue.  Watch out for worms such as W32.Sanper, which also
provide a built-in spam relay network.  Remove all of the
open mail relays and you are left with...lots of spam.

More at NANOG...  ;)

Thanks,
Rob.
