My understanding is there is no way to do that. How can you be sure that the pre-existing headers are genuine? They could have been added by a spammer, in order to make you beleive the message is safe and need no further checking. If you trust some customers to have a proven anti-spam solution, you could redirect their mail to completely by-pass amavis (or the SA part in amavis), but you leave them exposed to what their own anti-span can or can't do. best regards, Olivier > > <https://bugzilla.zimbra.com/show_bug.cgi?id=96532> has the general user > reports. > > Thanks, > Quanah > > -- > > Quanah Gibson-Mount > Platform Architect > Zimbra, Inc. > -------------------- > Zimbra :: the leader in open source messaging and collaboration > --
