clamav ports

[Bart Silverstrim]

I've emailed the maintainer about this a few hours ago, but wondered if
  anyone else had experienced this...

I'm running postfix with amavisd-new and clamav (clamd) to scan
incoming email from the Internet then forward it to an internal Exchange
server (a spam/virus filter server, essentially).  I just finished 
updating to
  the latest 4.9 bug fixes, and afterwards did a portupgrade of my 
installed
ports.

Clamav was updated to the latest version, and now clamd is missing
some viruses that it was catching before (and clamscan, I believe, can
still catch...somefool.b-petite, for example).  The version is 0.67-1.  
It is
  still reporting that it is quarantining some viruses, so I know it is
"working", but I don't know why it would have just "stopped" catching
some of the emailed viruses.  Anyone else run into this problem?
Is there a new setting that I'm missing?

I wanted to post this question to the clamav-users list, but I 
subscribed late
last week and while I get the messages it says I'm a non-member and 
posts
are held for moderator approval, and I haven't heard anything from the
moderator after three messages to the list and one to the address that I
thought might be a maintainer's address :-(  I thought it could be 
somewhat
FreeBSD related since it just started happening after I upgraded from
ports, though.
