I'd be interested if anyone can correlate what I've seen: we have 2 MX
records, one weighted at 10 (primary) and one at 20 (secondary). Of the
200 or so MiMail's we've seen 100% have come through our SECONDARY mail
server. Maybe the SMTP engine was written poorly, or maybe it was this
way on purpose?

There is a list of SMTP servers that, once infected, the virus will scan
the infected system looking for valid emails, store it in "eml.tmp"
C:\windows dir, and once it senses an internet connection will forward
itself to everyone in the eml.tmp file via those external SMTP servers.
The virus writes the following key to make sure it runs at start up:
HKLM\Software\Microsoft\Windows\CurrentVersion\RunVideoDriver=C:=Windows
directory\videodrv.exe

Check for:
C:\Windows\videodrv.exe (payload)
C:\Windows\eml.tmp (list of emails the payload found to send itself to)
c:\Windows\foo.exe (installation file)
