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?

Thank you.
