Are we getting hit with massive amount of spam?
- Message Count last 48 hours 300,000+ (mta_count(msg)). This is usually in the 7,500 range.
- Message Volume last 48 hours 4,500,000,000 (mta_volume (bytes)).
- Anti-Spam/Anti-Virus Activity last 48 hours 250,000+. Usually below 10,000 - more like ~2,000.
All swap gets consumed. Load averege 60.00+ - server becomes unresponsive.
It seems that when I start the postfix it starts feeding the email to amavisd and that's what uses all the resources.
(Upgraded to 6.0.7_GA_2473.UBUNTU6, but still can't start the system without getting it stuck again.)
Is there a way to limit the resources amavisd uses?
Where to look if it's single email address/domain that gets all this email?
Any tips to get this sorted?
