I want thunderbird to block TOP LEVEL domains. This does '''not''' mean ([email protected]) or (example.com) '''This means .com''' I have a huge list of Top Level domains I need to completely and totally block ALL emails from. I cannot block domains. That is a useless effort for 4 reasons: 1.) The Top Level Domain called .space (among other in my list) use spam email addresses such a example.space This gives them an INFINITE number of email addresses to use. There is NO way to block them other that at the TOP LEVEL. 2.) Blocking just the Domain ([email protected]) is also useless... read reason #1 3.) ICAAN has made it much easer for spammers to create unique top level domains. .... read reason #1 4.) My email provider does not and will not provide me options to block any Top Level Domain I choose. Its beneath them to provide such an essential tool. So, How can I set up Thunderbird so that it will totally block and Never download from my mail server ANY top level domain that I choose??? I dont want to know about using other email programs. Just provide me a method, tool, app, add-on, shareware, or whatever that will let me use thunderbird to block TLDR's
