Exim 4.54:

My Exim is rejecting email from my fax services efax.j2.com:

2006-03-22 17:28:43 H=(efax.j2.com) [216.43.6.98] listed invalid HELO.
2006-03-22 17:28:43 H=(efax.j2.com) [216.43.6.98] temporarily rejected MAIL
<message@???>: host lookup deferred for reverse lookup check

Efax.j2.com had been able to send me email in the past
(although I had placed exceptions for them in

 helo_lookup_domains   = !efax.j2.com : etc : * 
 helo_try_verify_hosts = !efax.j2.com : etc : * 
 host_lookup =           !efax.j2.com : etc : *

This server is NOT (currently) reversible in DNS,
AND the server A record for that name resolves to
a different IP address.

Although, I have sent an email to the admin of their
DNS, how can I arrange to accept email from this server
in spite of these problems?
