Hi, I have an interesting behavior of exim on Debian regarding multiply existing headers - but it also may be something really stupid.
This is my exim: |Exim version 4.80 #2 built 24-Jul-2014 03:28:02 |Copyright (c) University of Cambridge, 1995 - 2012 |(c) The Exim Maintainers and contributors in ACKNOWLEDGMENTS file, 2007 - 2012 |Berkeley DB: Berkeley DB 5.1.29: (October 25, 2011) |Support for: crypteq iconv() IPv6 PAM Perl Expand_dlfunc GnuTLS move_frozen_messages Content_Scanning DKIM Old_Demime |Lookups (built-in): lsearch wildlsearch nwildlsearch iplsearch cdb dbm dbmjz dbmnz dnsdb dsearch ldap ldapdn ldapm mysql nis nis0 passwd pgsql sqlite |Authenticators: cram_md5 cyrus_sasl dovecot plaintext spa |Routers: accept dnslookup ipliteral iplookup manualroute queryprogram redirect |Transports: appendfile/maildir/mailstore/mbx autoreply lmtp pipe smtp |Fixed never_users: 0 |Size of off_t: 8 |Configuration file is /var/lib/exim4/config.autogenerated This is the message: |From: Marc Haber <[email protected]> |To: Marc Haber <[email protected]> |Subject: Re: subject |X-Spam-Score: -4.2 |X-Spam-Score: -4.4 | |this is the message body My exim is running with a system filter: |# Exim Filter | |headers add "${if !eq {$h_x-malware-found:}{}\ | {X-torres-Malware-Found: $h_x-malware-found:\n}{}}\ | ${if !eq {$h_x-spam-score:}{}\ | {X-torres-Spam-Score: $h_x-spam-score:\n}{}}\ | ${if !eq {$h_x-spam-report:}{}\ | {X-torres-Spam-Report: $h_x-spam-report:\n}{}}\ | ${if !eq {$h_x-spam-checker-version:}{}\ | {X-torres-Spam-Checker-Version: $h_x-spam-checker-version:\n}{}}\ | ${if !eq {$h_x-spam-status:}{}\ | {X-torres-Spam-Status: $h_x-spam-status:\n}{}}\ | ${if !eq {$h_x-spam-level:}{}\ | {X-torres-Spam-Level: $h_x-spam-level:\n}{}}\ | " |headers remove X-Malware-Found:X-Spam-Score:X-Spam-Report:X-Spam-Checker-Version:X-Spam-Status:X-Spam-Level | |headers add "${if !eq {$acl_m_malware_name}{}\ | {X-Malware-Found: $acl_m_malware_name\n}{}}\ | ${if !eq {$acl_m_spam_score}{}\ | {X-Spam-Score: $acl_m_spam_score\n}{}}\ | ${if !eq {$acl_m_spam_report}{}\ | {X-Spam-Report: $acl_m_spam_report\n}{}}\ | " And this is what is delivered to my Inbox when I feed the message to exim on the command line or via SMTP using swaks --data: |From: Marc Haber <[email protected]> |Subject: Re: subject |To: Marc Haber <[email protected]> |Date: Mon, 27 Apr 2015 19:48:06 +0200 |Return-path: <[email protected]> |Envelope-to: [email protected] |Delivery-date: Mon, 27 Apr 2015 19:48:06 +0200 |Received: from root by torres.zugschlus.de with local (Exim 4.80) | (envelope-from <[email protected]>) id 1Ymn8Y-0003NJ-R8 for | [email protected]; Mon, 27 Apr 2015 19:48:06 +0200 |Message-Id: <[email protected]> |X-torres-Spam-Score: -4.2 | |-4.4 | |this is the message body Please notice that the contents of the two X-Spam-Score headers get folded into a single one, with an empty line between the two instances, and the second content without a leading space. This makes other software think that this is the end of the headers, and the rest of the message is placed in the body. exim -d+all yields the following: |19:49:24 13145 condition: !eq {$h_x-spam-score:}{} |19:49:24 13145 result: true |19:49:24 13145 expanding: X-torres-Spam-Score: $h_x-spam-score: |19:49:24 13145 |19:49:24 13145 result: X-torres-Spam-Score: -4.2 |19:49:24 13145 -4.4 |19:49:24 13145 Is this the intended behavior? Is it the result of some misconfiguration? Is it a (known) bug in Exim? Is there a fix/a workaround? Greetings Marc, who hasnt straced Exim in a decade -- -------------------------------------- !!
