So far: 8 unique spammers GL'd (GreyListed), a 9th got past but was rated 28.7 by SA. 1 of the 8th spammers has been firewalled - trying a DoS-style attack (250~260 SMTP connections between when greylisting was activated and when I firewalled them off) - greylisting started at 11:49, Sept 24, started spamming at 18:51, firewalled at 23:50.
Genuine email is getting through, spammers who can't be bothered re-trying aren't, and the only one who has gotten through so far has been caught by SA. :D Looking good indeed as I'd have probably received 10~20 spam out of the GL'd hosts. I'll have to develop some means of sifting through the log files instead of doing it myself (unless someone else has already done this) - it took 30~60 minutes to sift through 12hrs of log file - I don't have the time to do that every day for a 24hr period - any suggestions/hints on what to do?
