Subject: [Exim] Domain Verify - Similar to Sendmail
Hello,
I am trying to enable an option in my configuration have Exim make sure
that the sender's domain exists in DNS. I believe this should be some form
of ACL, but something that does not use callout.

I'd like to do the following:

1. Look at the domain part of the MAIL FROM: command.

2. Do a lookup to see if NS records exist for the domain.

3. If so, accept the mail. If not, 550.

I'm certain I could do this in perl if I wanted to, but I'd like not to
have to call out to perl to do this.

Suggestions?
