It still works for me, but maybe I'm part of a lucky minority.  I've
been doing it for almost 26 years, after having registered my own domain
in June 2000, and for 23 of those years the server has had the same
static IP address (in an IPv4 /29 that I got from Zen).

It tends to be more reliable than sending via Zen, as their outgoing
mailservers occasionally get added to the various anti-spam blocklists.
Another advantage for important emails (e.g. to solicitors) is that
after sending I can check my logs to verify that the email was received
by the destination server.

Over the years I've had to make some config changes to be able to
deliver to the likes of gmail and yahoo, specifically setting up
reverse DNS early on, then SPF some time later, and more recently
DKIM and DMARC.
