Sounds good, this means your authenticator is correct. Do you
see 'AUTH' when you give the EHLO command?

This sounds like Eudora does not try to authenticate. First,
authenticated messages should have 'asmtp' as protocol in
Received: headers. Make the guy mail you and look at the header.
I wonder whether there's a way to log all SMTP commands.

Exim should see the hostname in DNS PTR records (the verizon.net
one, I believe). It should not matter, really.
