Disabling outbound email scanning

[MGSteve]

I'm currently sending out a mailshot and the Zimbra server is heavily loaded with multiple amavisd processes - I presume its scanning emails as they go out (or bouncing back I guess, quite a few will be).

Anyway, is there a quick and easy way to disable scanning of emails as they go out - I really don't see the point, as far as I'm concerned, the responsibility for email scanning should be the recipient's.

Steve.

lol, I have the same issue again, did a google search and found my old thread.

Is there an answer to this as its bringing the mailserver to its knees each time I sent a mailshot out.

This is an example of the 'top' output and using atop I can see the that box is really disk bound rather than CPU bound, although its a pretty close thing.

There will be a reasonably high level of bounces, so this will increase the load of course - these should drop over time when the code in the mail system removes them from the mailing list.
