Limiting access of SMTP to our Email server

Is there a way to only allow SMTP access through ASL from a specific domain name?

I can not use the IP address that the incoming email server resolves to because the IP address may change but the DNS name will always stay the same.

True that that example was for IPs, but I believe it can also work for domain names.

I am not an Exim guru, but maybe you can search on articles on the web using the mechanism that he used to filter?

Or maybe an Exim guru will spell it out for you here??

nospamsam,

ASL V5 allows you to define DNS objects. Unfortunately it is available as beta only at the moment.
