>Can you comment on this Scott? Any danger here?

The decompression of archived files is handled by the AV software, not 
Declude.  Therefore, the potential for a problem here would depend on the 
AV software that you are using.  Unfortunately, I don't have any 
information about how the various virus scanners handle this situation.

If the AV software is properly designed, in the worst case, it should 
handle the situation gracefully (immediately deleting any files it creates 
as soon as disk space is used up).  If this happens, the disk space will be 
used only temporarily.  This could potentially allow the one E-mail to be 
delivered, even if there was a virus in a separate attachment.  However, 
that would either require that the recipient open an attachment when there 
were two or more attachments present, which would likely be a "red flag" 
for most users (why would they be sent this second file that they don't need?).

This should not create a DoS situation.  The hard drive should only be full 
for a fraction of a second (if at all), which should only cause minor 
inconveniences (IE one incoming E-mail might get re-routed through a backup 
server, or a user retrieving their mail may get a temporary error message 
but get their mail when re-trying it).
