MailScanner 4.78.17 doesn't detect viruses, have checked tmp permissions and no symlink, reinstalled clamav (worked in 4.77.10)

[Sunny Forro]

Rich, thanks for the reply.

I've gone through and checked the versions of all the perl-tars against
what's installed (and reinstalled some of them to make sure the versions
match). Everything that I've checked matches the expected versions for
this release of MailScanner.

Check your virus.scanners.conf file to ensure it is pointing at the 
correct place for clamav.
If "which clamscan" reports /usr/local/bin/clamscan then the clamav line
 
in virus.scanners.conf should end in "/usr/local" and if it reports 
/usr/bin/clamscan then the line should end in "/usr".
 
That would be the first place to look. Then "MailScanner --lint" should 
detect the EICAR test pattern successfully. Once "MailScanner --lint" 
works, you're there.

Jules, thanks for the reply!
I checked "which clamscan" and yes it does point to
/usr/local/bin/clamscan. The clamav line in virus.scanners.conf does end
in /usr/local. Still no lint under 4.78.17, but works fine under
pervious versions on the same box. Using clamav-wrapper to do a scan of
/tmp gives me sensible output however.

MS4.78.17, 
	SA3.2.5, Clam0.95.3, sendmail 8.14.3 on FreeBSD7.0p9, w/
mailwatch 
	1.0.4, apache13, mysql5077, php5, virtualized through VMWare
VSphere 
	4.0. I've switched back to 4.77.10 as this properly identifies
virii.

This may be totally unrelated but I had a similar problem like this at
one point.  It turned out that the perl I was running had version 0.16
of perl-File-Temp builtin and the version that came packaged with
MailScanner was 0.19.  When perl was updated v0.19 was removed.  I ended
up having to do a rpm --force on the version that came packaged with
MailScanner.

This is all from vague memories and I may not have the scenario exactly
right.  It took me a while to find it though.  Check the version of
File::Temp that you are using.  I know that once I got the correct
version installed MailScanner --lint started producing expected results
with my virus scanners.
