If I have a user that is on a Verizon DSL. They go to email me from their Outlook Express, and they login to my server to send mail. Doesn't their mail client send a HELO/EHLO to my server when they go to send?
Correct.
And wouldn't it be an IP address and/or a in-addr.arpa PTR when they connect?
No reverse DNS entry should point to an in-addr.apra address (although some are incorrectly set up to do so). Most likely, the reverse DNS entry would point to something like "HOST-192-0-2-25.example.com".
