The clue is in the error log. It says you must use "-t" or specify the
recipient on the sendmail command line. In the case the message is
detected as spam, you do this:
$SENDMAIL -f [EMAIL PROTECTED] < /var/tempfs/out.$$
There's no -t and no recipient. The -f option is the "from" part. I
suspect you want to send spam to [EMAIL PROTECTED], in which case
try something like this:
$SENDMAIL -f $2 [EMAIL PROTECTED] < /var/tempfs/out.$$
$2 should be the sender, as passed into the filter script.
Rather than calling spamc on each message, you might also consider
a daemon solution which will reduce the overhead and startup delay
time. Very helpful if processing a lot of mail. I use amavisd-new
and have it run clamd before spamassassin. There are others that
have been mentioned in this mailing list, as well.
