That was part of my spam checks but had to disable it because Microsoft
Outlook is not RFC compliant in that respect. I haven't actually checked
to see where it's failing, but one of these directives--although correct
RFC wise--will bounce legit mails from Outlook:
deny
message = Your message does not conform to RFC2822 standard
log_message = message headers fail syntax check
!verify = header_syntax
deny
message = Your message does not conform to RFC2822 standard
log_message = missing message headers
!hosts = +relay_from_hosts
!senders = :
condition = ${if or {{!def:h_Message-ID:}{!def:h_Date:}}
{true}{false}}
Never bounces email from any other client...only MS Outlook.

I think it must be the Message ID that's failing. We use header_syntax
checks, but have some Outlook users. Some Exchange servers leak messages
with bad header syntax, though ( I think).
