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?
You can get a mailprovider that allows custom domain names for very little money. I use Mailbox.org and it works fine. Also used Protonmail previously which also works.
Mailcow includes rspamd which learns spam using bayes analysis. Just move messages to the junk folder and it learns, after a month or so of training I get very very little actual spam, and no false positives.
lol may I ask what you have to do to get that amount of spam? I at most get one spam mail per month to my server and I have some addresses listed as contact information on my public websites.
