@kemonine Currently I run my email from home in a less than ideal condition. My ISP provides an SMTP proxy server which I can use, and with that configured everything works. However, this makes me entirely beholden to another server and if the ISP stops providing that then it's game over.

I first started running my own email server around 2011 and everything worked up until around the time that I started the Freedombone project around 2013. After that things have been becoming increasingly dire, with non-$bigcorp IP addresses often being blocked.
