I get a lot of spam on my servers which get detected by SA though are generated by innocent mail servers.
We see a lot of mail users have insanely simple passwords , spammers are using these accounts and send spam. By the time the administrator realizes the server has sent 1000's of spam If spamassassin had an option to send abuse report to servers automatically and send mails to abuse@<server-admin> the moment the first sure spam comes in the admin could be warned before much damage has been done. Obviously we limit to only 1 or 2 reports in an hour to a particular id Thanks Ram PS: I know having strict passwords is the solution, but any admin worth his job knows how difficult it is to get everyone change their passwords
