<aol> me too </aol> stats from last week's mail.log (from my home mail server which handles mail for about half a dozen people): 1 Bad HELO 10 RBL proxies.relays.monkeys.com 11 Recipient Domain Not Found 22 RBL relays.ordb.org 25 strict 7-bit headers 31 Relay access denied 32 RBL taiwan.blackholes.us 34 Sobig.F Virus 42 body checks 49 RBL spamdomains.blackholes.easynet.nl 56 header checks 61 RBL dnsbl.sorbs.net 182 IP Address in HELO 193 RBL brazil.blackholes.us 218 RBL blackholes.easynet.nl 271 Local access rule: Helo command rejected 342 RBL hongkong.blackholes.us 492 RBL dynablock.easynet.nl 924 RBL sbl.spamhaus.org 1080 Local address forgery 1099 Recipient address rejected 1133 Sender Domain Not Found 1771 RBL list.dsbl.org 1825 Dynamic IP Trespass 1902 RBL cn-kr.blackholes.us 2471 Local access rule: Client host rejected 3005 Need FQDN address 3581 Local access rule: Sender address rejected 4267 User unknown 25130 TOTAL Spamassassin stats: 382 spam 4093 clean 4475 TOTAL Percentages: spam:non-spam (25512/29605) 86.17% accepted spam (382/4475) 8.54% rejected spam (25130/25512) 98.50% i'm reasonably happy with that. 98.5% of all spam was rejected outright. only 382 spams (1.5%) made it through my postfix access lists, RBLs, etc to be tagged by spamassassin. these stats also demonstrate just how bad the spam problem has become. 86% of all attempts to deliver mail to my server were spam, ~25500 spams and ~4100 legit messages. if i wasn't blocking spam at the MTA, then at least half of those spams would have ended up in MY personal mailbox (or, more likely, tagged by spamassassin and saved into my spam.incoming folder)....about 13000 more spams than i currently receive. craig ps: i love postfix. it has the best anti-spam features of any MTA. pps: anyone who wants my simple spam-stats.pl script can get it from http://taz.net.au/postfix/scripts/
