Hi All, We are facing a situation wherein we are forwarding mails through a mail relay server. We have authentication set up for regular senders but for forwarded mails there is no authentication. On the relay servers, we want to track the senders using a specific x-header. We have figured out how to add x-header for authenticated users. However, for the forwarded mails, we are unable to find an optimum solution.
Is there any way to insert an x-header based on the mailbox/username of the forwarding (source) email address? Any help would be very much appreciated. Thanks in advance. -- Regards, Sridhar Kakkillaya -- ## List details at https://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/
