I see some of those as well. They are zombies in dynamic space. Major
increase from Charter lately. I assume that you are rejecting all of
these as dynamic. A 55x consumes very few cycles and
very little bandwidth.

The pattern I see from most of these is multiple streams attempting
to deliver to 46 spam traps which suggests a common mailing list.

We have a database on line which will allow you to see if these are
exploits also seen here ( http://tqmcube.com/spamquery.php ) which may
be of some help - or not.
