Exim Restrict outgoing relay by ip address
I am moving our email server from MS Exchange to Exim on Ubuntu 8.04.1. Version of Exim is 4.68.
As one of our security layers, we restrict authorization to send/relay email via our mail server from approved IP networks only. Whether this is a perfect method or not is irrelevant as it is but one of our security layers and we do not need to allow relaying from the world.
I need to be able to restrict the sending of outgoing email via our servers by IP but need to allow the receipt and delivery of inbound email from any IP.
I have spent over 2 weeks scouring the web, reading through the Exim specs and doc and other resources and have tried many many ways to achieve this goal but to no success yet and am becoming very desperate. I will need to give up on Exim if I cannot achieve this and have already invested a huge amount of time into this.
In summary:
* Restrict ability to relay outgoing email from our servers by IP (Normal encrypted TLS username/password also required of course)
* Allow inbound delivery of email from any IP
Does anyone know whether this can be done and if so how?
I would truly appreciate any help on this.
Regards,
Jeff

CALIBRE-SMTP(1) 						      calibre							   CALIBRE-SMTP(1)

NAME

       calibre-smtp - part of calibre

SYNOPSIS

       calibre-smtp  [options] [from to text]

DESCRIPTION

       Send  mail using the SMTP protocol. calibre-smtp has two modes of operation. In the compose mode you specify from to and text and these are
       used to build and send an email message. In the filter mode, calibre-smtp reads a complete email message from STDIN and sends it.

       text is the body of the email message.  If text is not specified, a complete email message is read from STDIN.  from is the  email  address
       of the sender and to is the email address of the recipient. When a complete email is read from STDIN, from and to are only used in the SMTP
       negotiation, the message headers are not modified.

       Whenever you pass arguments to calibre-smtp that have spaces in them, enclose the arguments in quotation marks.

       --version
