This machine was set-up about 12 years ago, early 1998. It was supposed to serve as a mail-relay for the former students of the school, and was administered by some of them, on a voluntary basis. The machine was working very well, and SPAM were not that common in those pre-historic ages. :-] Since then, time has passed, and the machine became known to spambots. It suffered a very high-density attack early 2000, which ruined the school's network for two weeks. Unfortunately, one of the admin has gone MIA, a second one had migrated to the states, and the third and last one was on holiday. All former students that had a mail on this machine (virtually all, dating back to the `60s, that is... a lot of them!) got spamed beyond sanity... The machine was then configured to: - spam-trap with spam-assassin - check sender against known spammers and/or open systems - virus-scan the mails with ClamAV Except for a HW issue and complete replacement circa 2001, all went well for the past 10 years, without even a single admin loging in during as long as *7* years! But then... The ClamAV version we used was discontinued upstream on 20100415, last month, which had terrrible consequences... - the virus DB was corrupted on april 17th, when it was automatically updated with an incompatible version - consequently, all mails were treated as spam - ..and stored in the "bad list" by Spam Assassin - all sending domain were considered spammers, and blocked - every mail got dropped to the floor without notice - and then I noticed the silence from the outter space... :-/ It took three weeks to fix the issue, of which two to get in contact with a former admin, who absolutely did not care, but granted me root access. After a week trying to fix the issue in a VM (can't directly affect the machine, it's in production for other services), I finally managed to fix up the issue. But there still are some sending domain registered as spammers and/or messages accidentally match against the now improper "bad list", which I don't know how to fix... Sigh... Sorry for the long mail, but you asked! ;-P Regards, Yann E. MORIN. -- .-----------------.--------------------.------------------.--------------------. | Yann E.
