I really need to disable spamassasin and ClamAV on outgoing mail. Prefferably for mail originating from specific ip-addresses. If I try to send 10 000 email (a subscribed newsletter) the mailserver gets extremely slow with it enabled. Any idea on how to configure that? I know that I could set up a separate server for this, but I would prefer to be able to use the same mta as for other mail. Besides, I don't really see the need for it on outgoing mail anyway.
