Many of those bounces aren't real bounces, but spam messages with virus attachments.
we use Policyd (http://policyd.sourceforge.net/) with Postfix in front of the main mailserver (Plesk), and it offloads it significantly. Also the amount of spam has reduced dramatically.
We use also Policyd for rate throttling of broadband users, in order to limit their ability to send out spam through our server.

Hi folks,
We are currently experiencing a heavy load on all our smtp inbound servers since saturday.
It is due to bounces coming from everywhere. Spamers using fake email addresses from domains for which we are the MX.
The amount of such emails (which we almost all reject, user unknown, etc.. because of the fake email addresses) is enormous compared to normal traffic (like 10 times what we have in general).
Do any of you experience the same problem ?
