This is strange, I cannot find a code path which sets CC_BADH without
setting the minor > 0.
I think I'm using a version packaged for RHEL (2.12.0-10.el7), so it's
probably old, but other than that, I don't think I've done anything that
should change code paths.
How do I determine what exactly is wrong with the header that the
remote server is sending?
What is your log_level and do you see "check_header: " log lines?
$log_level = 1;
I don't see check_header in the logs.
What should I set it to?
If I can't get the remote site to fix their stuff, is there a way to
bypass the header check for their domains only?
If they DKIM-sign their mails, you can use author_to_policy_bank_maps
and disable header checks inside such policy_bank.
And if they don't, what's suggested?
Is there a way to configure the system to reject messages with bad
headers, but to do the rejection with a temporary, rather than a
permanent code, so that the the remote system should attempt the sending
again later?
