I've never noticed or heard of any false positives until now. I've
never had to ask the maintainer for anything, either, so I can't speak
to his/her responsiveness. We've been happily using it for a couple
of years without incident.
Is there any pattern to the false positives has File::Scan been
generating? Is it related just to the "suspicious file" detection,
or to actual signature data?

Not knowing any better, it seems to me that most folks would have
File::Scan installed entirely and only for use with MIMEDefang, but
I could be mistaken. Since its value seems to come mostly from its
"quick first pass" quality, I would think that it wouldn't be as useful
as Clam AV or some other free package for other uses.
In other words, I'm arguing that if someone has File::Scan installed,
perhapsy they almost always intend to use it with MIMEDefang, so the
extra step of having to enable it might be superfluous.

It's pretty simple to use $Features{"File::Scan"} as you suggest later
in the thread, so I won't lose any sleep over it.
If I had my druthers, though, one or more of us could try to talk to
the maintainer (Henrique Dias, hdias at aesbuc.pt) to get at the root cause.
I'll drop him a friendly note that directs him to this thread. If I
were him, I'd certainly want to know. :)
