AFAIK this isn't the case any more.

I agree, this is totally ugly. I have fixed that, well I have hacked a
version of AMaViS so that it can be called from a system filter, so
the messages are not removed from Exim's control at all. These changes
as well as half a more modular rewrite of AMaViS into proper Perl (in
some aspects the current codebase looks more like the quick rewrite of
the shell-script version *g*) are going back to the project.

I think I'll have a look at exiscan, too, then.
