Your reasoning sounds good to me -  but when tranferring email to his
ISP the header sequence gets written with "His" ISP's IP in the chain.

The combination of his IP and His ISP's SMTP relay IP may be what makes
the header get thru the filters as a "valid source", or the combo of
his IP and his ISP's mail domain may be what does it.

The combination of his dynamic IP and and any other SMTP relay is
clearly setting off alarms.

Other than that, I dunno.   :)

Whats the IP address of your SMTP server ?  Is it in any of the
blocklists?

You can check here:
http://openrbl.org/

Also try his IP address there to see who is blocking it.
