How does one do that? I searched the current Exim documentation for "in-reply-to" but found only one mention at Mail Filtering paragraph 3.14 (http://www.exim.org/exim-html-current/doc/html/filter.html) and that referred to creating a new email message. I wanted to pick-up the in-reply-to header and save the value in a self-created header but I can't find a predefined Exim variable for in-reply-to and $h_In-Reply-To (which is supposed to be identical to $header_In-Reply-To) is empty. For example: ... acl_smtp_data = acl_check_data ... acl_check_data warn add_header = X-ABC-Received: $tod_full warn add_header = X-ABC-In-Reply-To: $h_In-Reply-To warn add_header = X-ABC-Sender-Helo: $sender_helo_name warn add_header = X-ABC-Sender-Host: $sender_host_name Regards, Paul. -- -- ## 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/
