That's a good point.  I'm just using an out of the box (ish) version of
MailWatch to handle the releases, which doesn't add that header.  I feel an
enhancement request for MailWatch coming up ;-)  Documentation about best
practices will help here.

Releasing a file to a user and then having the release bounce back is a
cumbersome way to do things.

and from another post...

We do indeed, but the AV vendor lagged well behind ClamAV with updated
patterns, hence the window of vulnerability I mentioned in an earlier post.

I really don't want to go on about this.  I'd just like everything delivered
or quarantined scanned.

Well, everything, but if you are in an environment where you have a high
spam to ham ratio, you might feel differently.  But I've just covered this
in a different post.
