Sometimes I really hate #apple and the way the company dictates to the people that paid good money to buy the device how to use it. Apple effectively killed the self-signed certificate. I like self-signed certs for private systems but Apple's mail app refuses to use them, even when you add it to the trusted store????

I don't know. I did do an end run around the problem by using #letsencrypt. But Let's Encrypt is really designed for websites. I am going to have to figure out a way to periodically restart #postfix and #dovecot so that when the cert gets updated, it gets reloaded. Fun timez!
