Hello,

I am running clamav 0.95.2 with mimedefang 2.64 and sendmail 8.14.3 on Solaris 
10.  I am finding that messages with the following are not being detected by 
clamd, but are detected by clamscan as Trojan.Downloader-77566.

Here is what clamscan finds:


# clamscan ENTIRE_MESSAGE

ENTIRE_MESSAGE: Trojan.Downloader-77566 FOUND



----------- SCAN SUMMARY -----------

Known viruses: 623506

Engine version: 0.95.2

Scanned directories: 0

Scanned files: 1

Infected files: 1

Data scanned: 0.01 MB

Data read: 0.01 MB (ratio 1.50:1)

Time: 4.645 sec (0 m 4 s)

However, clamd (invoked from mimedefang) does not seem to pick this up at all.  
Other similar trojans such as Email.Trojan.GZC are being detected by clamd.  
Freshclam is updating the database normally.  Any ideas why clamd would miss 
something that clamscan detects?
