Good afternoon guys!
I have the following question:
I need to redirect all mail in the Subject containing the term "Test
Email" to a particular account.
Exim won't even see or care about the subject until the mail is received.
Once it's received you can filter it with exim.pl.

Or, in DATA phase, with either a lookup for any reasonably predictable
string, such as 'Test message' (or in this case uber-common spam):
===
# DATA_9: Check for forbidden strings in Subject: IF found THEN WARN
#
warn
condition= ${lookup{$h_Subject:}nwildlsearch{/var/filters/badsub}{1}{0}}
(set an acl_m variable here, and have a router/transport act on it)
NB: 'badsub' is an ordinary flat file, one-entry-per-line structure
===
ELSE with a regex ('trigger' is a less-predictably-placed sub-string, in
any of the 'Received' headers in this example, but that's easy to change):
===
# DATA_SCAN_01A1: IF message is from known spam-engine THEN deny
#
deny
regex = ^Received:: .*PowerMTA
(make this a 'warn' for your use, use it to set an acl_m to direct the
router/transport to where you want the message delivered)

Perl is useful - but best to save the overhead for the harder stuff...
