# SpamAssassin checks - only if mail <10000 bytes
# (spamd is running on port 2222 here)
:0 fw
* < 100000
| spamc -p 2222
:0 e
{
  EXITCODE=$?
}
:0H :
* ^X-Spam-Status:.*Yes
SPAMBOX

 - ":0" tells procmail that this is a new recipe
 - "fw" means that the action is a filter (and to wait until it completed)
 - "* < 10000" means that the message must be less that 10k in size
   (anything larger is usually not spam)
 - "| spamc -p 2222" tells procmail what to do with the message
 - the "e" recipe tests the result of the last action and if it
   failed then the EXITCODE is remembered (for later decisions)
 - if it has been tagged as spam by spamassassin by adding yes to
   its status header line, then it is delivered into a mailbox file
   called "SPAMBOX"
 - if it isn't spam, then it processed as usual.

There are several man pages for procmail, procmail(1), procmailrc(5)
and procmailex(5), there are plenty of good examples in procmailex.
