Hey all, I have a configuration that I'm putting in place for an
autoresponder. Following the wiki, it makes perfect sense, however,
I'm moving most of the logic into the ACL's instead of in the router.
During my testing, I've figured out that the header checks are failing
when they should be passing. Using this config snippet:
warn logwrite = DEBUG: Checking for List-Help header
condition = ${if def:header_List-Help: }
logwrite = DEBUG: Found List-Help header
This portion of ACL is in acl_check_content, which is assigned to the
acl_smtp_data configuration option:
acl_smtp_data = acl_check_content
I telnet to the server, do the handshake and then paste a valid email
into it with the following header:
List-Help: blah
The output in the log is:
2010-09-02 20:35:20 1OrGUz-0003m1-9t DEBUG: Checking for List-Help header
2010-09-02 20:35:21 1OrGUz-0003m1-9t <= tlyons@???
H=tlyons.ivenue.net (tlyons.ivenue.com) [192.168.100.166] P=esmtp

(parent@???) <parent@???>
R=virtual_user_old T=address_directory
The recipient shown above is a fake domain on our dev system. The
problem is that it should be detecting the header as existing. I've
tried with and without the trailing colon, with and without the
trailing space, with both h_ and header_, and with and without
uppercase leading letters. It just doesn't detect that this header is
present. Has anybody ever seen this before?

I'm still using 4.69 because I've not yet changed my configs to use
the new DKIM methods, so I'm still using the older libdkim linked
method. "In my spare time" is the answer for right now.
