Subject: [Asrg] [Fwd: Time to check the rate limits on your mail
servers]
About the attached message...
Both on NANOG and here on ASRG, many of us said many times,
and most of
the times people called me crazy;
1. Block port 25 for dynamic ranges - that will kill the
current strain
of worms.
2. It won't solve spam, and neither will SPF or anything else of the
sort, as when you have 100K zombies, you don't need to act a
server, you
can use the real credentials for the user, and even if
limited to a 1000
messages, that times 100K drones is...
The issue is numbers, and how to reduce them, not stop the tide.
Currently there is a discussion of this on Spam-Research [1], quite
interesting.
Gadi.
