Subject: Filtering on the cc line size
The recent batch of e-mail spammers seem to be fascinated with the cc line.
Is there a way to test the cc line and filter out mail if the line has an
unreasonable number of characters in it?
Try this (untested):
# Make CCLEN contain the number of chars in the Cc: line
CCLEN=|formail -X 'Cc:' | wc -c
# Throw it away if this is more than 200 characters.
:0
* ? test $CCLEN > 200
