I miss the days when you could just do [email protected] when signing up on a website, but now everyone either outright rejects it as invalid or parses it out.
It was useful because you could see who was selling your email address, but that exposed too many companies and was losing them $$$ so they patched it :(
pfSense is what happens when you take OPNsense and put a chick in it and make her gay and lame. Always go with open source.
