In a system filter, you can write
if ${perl{subroutine}{$h_subject:}{arg2}...} is "fail" then fail endif
In a user filter, which it looks like you are talking about, you can't
in Exim 3 use the "fail" command. But you can achieve more or less the
same result by a combination of "mail" and "seen finish".
However, since you probably don't want to allow all users access to Perl
in their filters, it may be best to use a separate director for
postmaster, so that you can enable Perl only on that one. If you do
that, you can also set allow_system_actions, which will make "fail"
available.
