[exim] Exiscan-acl and local scanning

Hello,

I have some people that have dialup accounts only that get mail to/from
me via UUCP. That, of course, winds up calling exim without using SMTP.
Exiscan-acl seems to only scan messages submitted via SMTP. I don't
care about spam checking messages submitted locally, but I do want to
virus scan them. Is this possible somehow?

Thanks,
John
