I went to expireddomains.net and searched for ones ending in “__mail.net”. Found a good, short domain that was once a regional ISP and email provider 15-20 years ago. (I still get spam for some of their old subscribers.).
I do not use subdomains for this one. Generally, I combine a simple name with a number for the mailbox name. Like “johnathan2715@zzzmail.net” if I think it needs to look like a real name, or some other word like “giraffe1238” or something like that.
It’s working great.
If that were true, then how do Brave and Librewolf even exist? Clearly it was less work to strip the garbage than to start from scratch.
