Tried using the check_mail ruleset located in chapter 29 of the O'Reilly
book and got an error message saying that $3 was out of bounds. Has
anyone used this ruleset? (It is for domain level blocking) If not, can
anyone else help me in blocking spam with sendmail (I would like to use
the rulesets if possible, but would also use procmail if that is more
efficient). I would like to do this mainly at the domain level, but if it
can only be done at the user level, this would be good also. Thanks in
advance.
