Nothing like responding to your own emails. :-)

I've modified the clamav-wrapper file by changing the ScanOptions= line
to the following:
ScanOptions="$ScanOptions --unzip -l /tmp/clamscanlog --log-verbose"

I now have a log entry in /tmp/clamscanlog each time a message gets
logged. Unfortunately the log tells me almost nothing. A typical entry
looks like this:
Scan started: Tue Jan 27 14:32:06 2004

And an entry where it finds an infected file looks like this:
Scan started: Tue Jan 27 14:33:21 2004


Even with "--log-verbose" enabled, I'm not getting the kind of
information in the log file that I get if I run clamscan by hand with
the same options. Not sure why.

I'm not any closer (yet) to figuring out why some infected files walk
right by the virus scanner.

If I find a file that was originally marked as spam--but not
infected--how do I resubmit the file back to sendmail so it gets
processed by MailScanner again? For example, I've got a file called
i0RNAtV30557 that certainly looks suspicious, but when it went through
MailScanner it only got marked as Spam.

Any further thoughts out there?
