Unfortunately Exim's local_scan API doesn't support it (see=20

You have to submit a feature request (for a LOCAL_SCAN_DROP return code and=
=20
the corresponding action) to Exim first. But I doubt that it would be very=

effective and/or efficient. By the time SA-Exim is run, the message has=20
already been transmitted and stored to disk. The spammer doesn't lose much =

having to reconnect. I think it would be better for SA-Exim to write a reco=
rd=20
to a file that can be checked in the ACLs in order to stop all further mail=
=20
before DATA for some time period.
