But this is a problem of a clueless configured virus scanner on the
remote side.
First, it makes no sense to send a warning out to the "sender", since
the "sender" is faked in almost all cases.
Second, even /if/ they send a warning, this warning shoud be addressed
neither to the From nor to the Reply-To, but to the Sender (which should
be somthing like majordomo-owner@listserver)

Just my 2 cents,

Rainer
