I want thunderbird to block TOP LEVEL domains. This does '''not''' mean (example@example.com) 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 (example@example.de) 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
