I'm setting up a new server. And with the death of "OS X Server" aka "Server.app", I've been doing everything by hand. Which isn't that bad at all really. apache config is super intuitive. Setting up a VPN server is very easy too. Configuring `pf` firewall is oddly quirky but has an easy config once you shake out all the bugs. It's all easy (if a little time consuming). But that brings it to Mail. I've run Mail servers under OS X Server since 10.3. It's been very easy. Now that that's gone, I'm a little lost. I don't really know where to begin. I've never set up my own mail servers by hand. Do I just need to install dovecot and postfix via Homebrew? Are there other pieces you need? Is there a better way to do this entirely? The other problem here is that it's virtually impossible to search for help on this topic. There are about 90 million help articles on the web about setting up mail accounts in mail clients. That is always what you get when trying to search for setting up a mail server on a Mac.
