[Spam] Blocking all TDL's unless .nl

[jep]

Hi,

Because of an enormous amount of spam on one of our pop accounts, we want to accept only mails from .nl clients. For all the other mails to the pop, we want to send an email that we do not read it.

For example, [email protected] mails something real, we block it and send hem an email that we do not accept mail from .com domains.

Is there any way to make this using the exim/directadmin setup?

Thanks!

Hello,

I'm not exactly sure how to accomplish it, but I'll say that a good place to start looking is in the exim access control lists:
