grep -c works. :-)

I specify a 554 SMTP error message in my spamhaus FEATURE setting:

FEATURE(`dnsbl', `sbl-xbl.spamhaus.org',
   `"554 Mail rejected - http://www.spamhaus.org/query/bl?ip="$&{client_addr}')

Finding rejections is easy (add -c for counting):

   grep 'www.spamhaus.org/query/' /var/log/maillog
