-D maxlen idcache
Formail will detect if the Message-ID of the current message has
already been seen using an idcache file of approximately maxlen
size. If not splitting, it will return success if a duplicate has
been found. If splitting, it will not output duplicate messages.
If used in conjunction with -r, formail will look at the mail
address of the envelope sender instead at the Message-ID.
This from formail's man page. The magic is all done in there. The flags
used by procmail will feed the message header to formail. If formail has
seen the message, it will return success. Procmail will then consider the
message to have been delivered, effectively throwing it away.
If the message has not been seen, formail will return failure, and
procmail will fall through to the next applicable recipe.
