Betreff: [exim] Exim config question - accept SMTP from specific hosts
Greetings All,

I am sure this has been asked and answered before. Color me stupid...

I want to configure EXIM to only accept email from a specific host plus
authenticated users.
I am not sure what the right terms to use are, so I apologize in
advance.

E.G. I have a mail server that performs SPAM and VIRUS checking of
inbound emails to users. I want to configure EXIM to only accept emails
from that server + any valid user.

Basically
Access = xxx.xxx.xxx.xxx;+relay_hosts

So here is what I have:

acl_smtp_helo = check_helo

begin acl
check_helo:
  deny message = Your system is not allowed 2 send \
                     email via this server
       condition = ${if match {hosts = !xxx.xxx.xxx.xxx} \
                     {\.} {no}{yes}}
  deny message = Your system is NOT allowed to send \
                     email via this server
       condition  = ${if match {!+relay_hosts}\
                             {\.} {yes}{no}}
  accept


Or, if someone has a better method of handling this... I am very open
to suggestions:
Thanks in advance for your help.
Jim
