You can do a ratelimit keyed on any expression in an ACL.
you could do a ratelimit on ${h_subject:} in the data ACL.
once stuff gets into the queue it's harder to corral
Some spams have recipients email address in the subject, and so
all have sifferent subjects.
I feel that the best approach is to only work on known values and to
ignore things that are unpredictable.
