Hi,

We filter all our email though an outside anti-spam company. This service then delivers our email as per normal to our server. However what is also happening is that some annoying companies are delivering striaght to our email server bypassing the anti-spam.

In addition to that we allow users outside to connect to email via imap accounts and send using smtp on our server.

Is there any way of stopping inbound smtp connections to our mail server except from our anti-spam company and allow our users to send email from outside.

We are using Imail 8.05

many thanks in advance

Paul

You could set your control access to deny all except the IP addresses of service you use and your users.

You are asking for, perhaps, more than you realize.  You want wildcard addresses to be able to connect, and yet...you want to block wildcard addresses!

Your choices are three:

1) Run your server on a port other than 25, if your mail scanning provider can forward to a non-well-known port, and set up your MUA clients to hit that different port.

2) Restrict direct connection to your server to the scanning provider's fixed IP addresses only, and require a VPN for anyone else.

3) Restrict direct connection to your server to the scanning provider's fixed IP addresses only, and implement a second server that is used as a submission-only server (preferably on port 587, the WKP for this service) for anyone else.  This submission server will require authentication for all attempts, since all domains will be remote to it.
