Quarantined Mail ???

[broderic @ zergo . com (Stuart Broderick)]

I'm attempting to design and configure a firewall where any mail 
containing an attachment is forwarded to a 'quaratine area' where 
the mail can be inspected for viruses etc prior to being sent 
to the internal network.  

Does anyone know of any tech papers/faq's/descriptions/software 
needed to do this ?  Any pointers appreciated. 

Does anyone know of any UNIX based virus detectors which will 
catch PC (dos) viruses ? Firewall hardware platform currently not 
set. 

(Apologies if these questions have been asked before) 

Thanks
