Each message header or message body line is compared against a list of
patterns. When a match is found the corresponding action is executed,
and the matching process is repeated for the next message header or
message body line.
Note: message headers are examined one logical header at a time, even
when a message header spans multiple lines. Body lines are always exam-
ined one line at a time.
Postfix does not reasd the entire message into memory. That does
not scale well.
