Mail Proxy

Ive been fiddeling with nginx’s mail proxy features. I would like to
know if
its possible for nginx to proxy mail from non-authenticated senders
(incoming mail - MX records)?

Hello!

Yes, in 0.7.22+. You’ll need

smtp_auth none;

and appropriate authorizer script which will check
Auth-SMTP-Helo/Auth-SMTP-From/Auth-SMTP-To headers instead of
normally checked Auth-User/Auth-Pass.

Is there any example script for this (preferably in php)? If there isnt,
is
there any documentation (Ive read the mail core but it doesnt document
these
headers) and ill make a simple PHP script example if I can.

Im guessing Auth-SMTP-To is the backend SMTP server
as for the other two im not sure their role.
