Sendmail Access DB TLD Blocking ....
Now this is a bit tricky, but works great if you can decide which Top Level Domains or TLDs you want to receive mail We are getting so much spam from countries we never receive useful mail, I've been experimenting with blocking entire TLDs using sendmail access_db as an antispam technique.

Here is my current list, working great... yes I might miss a good one, but it blocks SO MUCH junk :

Code:
