Problem relaying for non local domain name

[Jean-Luc Tardivel <tardivel@dns.cnet-caen.fr>]

Hello,

I have to relay mail for an outside host. In smtp-policy.src i gave his
address _our_network rights. Zmailer accepts to relay only if sender
address in MAIL FROM: is our domain name. Is it possible to let them
give a valid adress whith a different domain name. I cannot guess which
domain they will use.

Zmailer 2.99.50-s7

Thanks for help

Best Regards
