If i understand this correctly, the device is (apart from being the least secure thing ever) basically useless at it's function, since it doesn't support SPF/DKIM/DMARC and you can't get it to use HTTPS and as such will bounce off every single correctly configured email server in the world?
If i remember correctly, when i tried to setup my own email server with my domain on a VPS box, i had to go through the whole nine yards of getting a letsencrypt cert and setting up lots of voodoo stuff before i could send mails to anyone but myself.
Also, how are you supposed to use this at home at all, if most residential ISPs (at least here in germany) block any Port 25 traffic?
