Short answer: no; it's primarily a limitation of the way SMTP works rather
than Exim.

Long(er) answer: for cases such as those you're suffering from (caused by
viruses) there is at least *something* you can do. Myself and a few others
have put together a bunch of SpamAssassin rules which do a fair job of
stopping both bogus notifications and (to a lesser extent) bounces caused
by viruses:

There are many variations available on the net, both for SpamAssassin and
various MDA's etc.

It's neither a very elegant nor good solution, but it works (to an
extent).
