Definitely exciting to see another very promising modern mail server option that seems to really be developing nicely. The major pain of self-hosting email for a long was ensuring delivery, but with SMTP relay services also getting quite slick that doesn't seem as much of a blocker anymore. Also means being able to clamp down even more tightly on the mail server at the network level as well as its own security since it only needs to talk out to the relay service and nothing else. In an ideal world there'd be a real solid secure DNS and in turn full e2ee email-like standard itself, and authentication could at least be one by certs in DNS.<p>But in the meantime email still fills an important role, and perhaps enough layers of options will get us close. After the Gandi.net sellout most recently this feels like propitious timing to me, I really dislike the typical email service pricing models. Paying just for the domains and relay, both of which are trivial to swap around at will, and then otherwise having that on my own infrastructure certainly feels attractive to try firing up again at least for a handful of domains.
