Does anyone know what code to use to block an entire tld? I know it's considered bad practice but in this case I don't believe it is.
We're getting an enormous amount of spam from the .faith tld which is an el cheapo tld. I've contacted the .faith registrar but they don't care so I'm happy to block it completely from our servers.
Normally I would just go into Webmin > Servers > SpamAssassin Mail Filter > Denied Addresses and enter a wild card for all emails coming from a certain address but it's too time consuming for this tld.
