We have been using always_bcc=maillog@domain, but now I need to exclude 4 email addresses from that. I know I could use the filters from the web interface, but I'm afraid of the users that are suppose to monitor the catchall account, disabling the rules and view the email from those 4 email addresses. Does anyone have any ideas?

So what I want to do is send all my from @domain.com to maillog@domain.com, except for user1@domain.com, user3@domain.com, user88@domain.com, user2@domain.com.

Can I do that? I'm using the open source version. 5.0.2. Thanks for your help.
