From: Paul Beard on

I am getting no inbound email after locking down the requirements of
users to authenticate before sending. I dropped back from current
(2.7.*) to 2.6.5.

Not having any success getting tcpdump output. The version I have
differs from the example in the DEBUG instructions.

Complete error messages. Please use cut-and-paste, or use attachments,
instead of reciting information from memory.
