New Mass Mailing Virus making rounds?

[Rose, Bobby]

Is anyone aware of a new virus making rounds?  The number of rejected smtp connections on my MXs went thru the roof around 8pm EST Sunday night and into today.  Rejections are due to no PTRs and obvious bogus non-existing domains in many causes hundreds of random return addresses from the same sending IP.

I googled and such and I'm not coming across any discussions of some new worm so now I'm curious if any other MailScanner users have seen this and have any info.
