A little heads-up about SoBig.F ...

2,000 of my inbound e-mail messages today has been this virus, from a
variety of sources.

The messages are the virus itself, neutered versions of the message, and
bounces/warnings from dummy antivirus software on mailservers out there that
still warn the sender, without regard to whether the virus it is warning
about is a mass-mailing from-address spoofing bit of malware.

The virus has its own SMTP engine, and puts this in the header -

X-MailScanner: Found to be clean

presumably to get past text filters that try to whitelist a message based on
this header.  MailSniffer is apparently a well-regarded and widely used open
source solution:

There is also a header line that mimics Outlook Express.

And the messages fail BADHEADERS, despite the "care" put into it by the
author!
