Hi,

I have a folder (mbox folder under PINE) in which I've kept a few virus
messages around to help me with scan testing. There are 8 messages in
there. I currently run RAV antivirus on another box, and if I scan that
folder (the mbox file) with ravav I get this:

/home/r.../viruses->(part0001:)->(IFRAME0000) Infected: HTML/IFrame_Exploit*
/home/r...il/viruses->(part0002:DOCS.DOC.pif) Infected: Win32/[EMAIL PROTECTED]
/home/r...uses->(part0004:Officiants.doc.pif) Infected: Win32/[EMAIL PROTECTED]
/home/r...viruses->(part0006:ME_NUDE.MP3.scr) Infected: Win32/[EMAIL PROTECTED]
/home/r...l/viruses->(part0007:SETUP.DOC.scr) Infected: Win32/[EMAIL PROTECTED]
/home/r...s->(part0008:www.myparty.yahoo.com) Infected: Win32/[EMAIL PROTECTED]
/home/r...s->(part0009:www.myparty.yahoo.com) Infected: Win32/[EMAIL PROTECTED]
/home/r...uses->(part0010:Officiants.doc.pif) Infected: Win32/[EMAIL PROTECTED]
/home/r...11:)->(part0001:Officiants.doc.lnk) Infected: Win32/[EMAIL PROTECTED]

Infected: 9. Different virus bodies: 4.

So in the 8 messages it found 9 viruses.

Then I tested clamav in 2 different ways, one where I ran clamscan on the 
mbox file itself, the other where I forwarded each message individually
to another account, and then later manually ran clamscan on each
individual message (messages stored in maildir format, so ran the files
individually through clamscan).

Here are my results:

# cat /tmp/viruses.mbox |clamscan --mbox -

----------- SCAN SUMMARY -----------
Known viruses: 7286
Scanned directories: 1
Scanned files: 6
Infected files: 3
Data scanned: 0.38 Mb
I/O buffer size: 131072 bytes

So with --mbox, it only finds 3 of the 9 infected.

With individual file scanning, NO viruses are found... :-(  how can that be?
