Sobig.F resurgence

[Mike Kercher]

In sendmail.mc, I added this:

This was suggested on the list several days back and has been working very
well.
May I remind you that the white gaps in text above are tabs and not simply
spaces.
Run your .mc through m4 and then restart MailScanner.

Mike,

Just curious... 
What Sendmail rule are you using to block them?
We've been rejecting the most offending IP addresses with the access
database, but as you might expect... It's a little like a moving target.

The flow here has been trickling but steady.  I am blocking LOTS of tehm
with a sendmail rule though, so they never even make it to MailScanner.

Hi All,

A little off topic, but we've started noticing about a 10 fold increase in
Sobig.F traffic over the last 48 hours.

Is anyone else noticing this?
