Mouss,
this could be a solution... but haven't find any example or documation to try it.
Could you pount me at any example?

The initial problem was:
I've an SMTP server for customers, with standard smtp open only from a range of IPs.
Could I provide normal smtp service for customers of a range of known IP (like now) and open my server to all the world
for smtp service but ONLY if autenthicated smtp i sused?

Is the MUA with an IP of my customers?
YES: It can send without any authentication.
NO: It can send ONLY it a user/pass is provided.

Simon
