Email self-hosting

As the title reads, I really want to begin hosting my own email server again. I'm sick of the poor quality of the service providers out there. Damnit all I want/need is a reliable IMAP/SMTP provider. I spent 3 hours getting off of Hostinger and on to Zoho. I just hope Zoho won't suck. It's great for now but we'll see.

Is the prevailing advice still not to bother with self-hosting email?
