I agree with Bowie. spamc has a default upper limit already. Anything
larger will be written to a file and then returned. If you want to save
yourself that disk I/O, you can use a rule like yours. I suggest,
however, that you specify the size limit so that you don't pass in the
odd message larger than the default, but smaller than your limit:
SPAMSIZE=500000
if($SIZE < $SPAMSIZE)
{
exception {
xfilter "/usr/bin/spamc -s $SPAMSIZE"
if(/^X-Spam-Status: Yes/)
{
to ./Maildir/.Junk/.
}
}
}
