We are running an SMTP gateway server with Exim version 4.43 with
SpamAssassin and ClamAV installed.
Lately, we have been receiving obvious spam messages that are not being
caught by SpamAssassin.
To combat this, I wish to create lookup file containing the list of
common words normally found in spam messages.
I want Exim to search the body and header of inbound mail and compare
against the lookup file. If a match is found, then those messages should be
quarantined or bounced.
