Nothing like a new release to remind me about the pain of migrating custom patches to each release. If you would like to incorporate this in a future release, please do.
I wanted specify which header sender field to verify, I've expanded the verify=header_sender command. I also fixed some of the header syntax checking to recognize some additional valid, and sometimes used, address list formats. http://www.donelan.com/exim-patches/header-verify.patch http://www.donelan.com/exim-patches/header-verify.readme verify = header_sender[=header_type]/<options> Header type can specify which "sender" header field to check. * returns true if any sender header address is verifiable all returns true if all header sender addresses are verifiable from returns true if verifiable address in From: header line reply_to returns true if verifiable address in Reply-To: header line sender returns true if verifiable address in Sender: header line The default action is "*" which is the current (4.70) behavior. Example from EXIM configuration # Check if just the header From: can be (partially) verified warn condition = ${if def:h_from: {true}{false}} !verify = header_sender=from logwrite = X-Header-Error: $acl_verify_message add_header = :at_start:X-Header-Error: \ could not verify "From:" header address -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
