There is a new trojan class out the that sends out the binary attachment as
part of a nested MIME message with boundary strings that are identical
rather than different as *required* by RFC.

As usual, Outlook in it's infinite wisdom decided to "guess" what to do with
such messages, whereas reformime ignores the bad attachment: end result - no
virus saved to disk - Q-S calls AV which then misses the virus...

This really isn't a fault of reformime, it's supposed to be a MIME parser -
not a "find all dicky messages out there" parser. 

As such I'll have to think of some way of doing this within Q-S, however all
is not lost. If you have a decent antivirus system, simply enabling
"--redundant yes" when "./configure"'ing Q-S should mean that after trying
(unsuccessfully) to find the virus/trojan, Q-S will then call the AV on the
"raw" mail message instead of just the attachments, and it may (depends on
what you're running) pick it up. Note that this will add load on your system
as now the AV effectively double-scans each message.

My plans for correcting this are:

* try out other options besides reformime - they may catch it (easy)

* accelerate Q-S v2 development, as it already partially contains this
  functionality (harder)
