I also reached out to them on Twitter but they directed me to this form. I followed up with them on Twitter with what happened in this screenshot but they are now ignoring me.

    TLDs are valid in emails, as are IP V6 addresses, so checking for a . is technically not correct. For example a@b and a@[IPv6:2001:db8::1] are both valid email addresses.

      I feel like using a@[IPv6:2001:db8::1] is asking for trouble everywhere online.

      But its tempting to try out, not many people would expect this.

        try [email protected] or user@d.e.a.d.b.e.e.f.0.1.2.3.4.5.6.7.8.9.a.b.c.d.e.f.0.0.0.0.1.2.3.4.ip6.arpa just for the giggles. Mix it with BANG-Adressing:

      Jeez and I feel like I’m tempting fate just by using a custom domain.
