Aside from semi-charitable organizations like that, I wouldn’t expect good free email service to exist.  It’s seriously complicated to run a properly-configured email server.

The last time I looked into it, there were something like 24 separate RFCs an SMTP-only server had to implement, and much of that complexity spills over into the administration side, such as DKIM setup.  Then you have everything outside of the protocol such as spam filtering, blacklist/greylist/whitelist maintenance, TLS key updates, OS updates, etc.

Expect to pay for what you use, either by throwing a whole lot of your own time at it or paying someone to spend that time on your behalf.  Unless you’re doing this for educational or professional reasons, where the time spent is paid back handsomely, it’s probably a better trade to pay someone to handle it for you.
