My guess is this is the botnet resulting from the storm worm variants going into
I've been noticing a lot of activity too. For the first time ever my sendmail
actually hit my confMAX_DAEMON_CHILDREN limit.
A lot of them seem to be "hanging around" in the command read state, so I added
a confTO_COMMAND limit of 10 minutes (default is 1 hour). Yes, I know you have
to be careful shortening this, but 10 minutes between SMTP commands is still
pretty reasonable, and hopefully will help my server shed these dead connections.
