Difficult to host smtp?! That's absolutely not true and has never been true. It's difficult to configure and set up in the first place but after that it's just updating. Source: personal experience for decades.

It's not like you'd notice the email you're not receiving, so I'm always a little leery of these "it works perfectly for me!" stories for email stuff.

I though the issue was with getting your mails accepted. Even gmail has no problem sending email to a server that isn't properly set up as long as it is willing to accept.

Can you mention (or link to) situations where gmail refuses to send mails to another domain?

But it's not just postfix or sendmail you need to configure correctly and then put apt-get update/upgrade -y in cron to avoid the damage caused by making a mistake or falling asleep at the wheel. Casual self-hosters have other vectors of attack to mitigate, for example making sure sasl or whatever they may be using for imaps auth is solid, that passwords are strong and routinely changed, that php is also tight and so on. The stakes are relatively high, the efforts to compromise systems for this and other purposes are voluminous and incessant. So I'd say "it takes a village" to do this safely enough, not individual enthusiasts who cannot commit to administering a server diligently.

Any tips for somebody looking to move to my own smtp server? It's been on my mind a few months, and I want to move away from gmail to my own server or to another service, preferably one I pay for.

I personally use OpenSMTPd for SMTP and Dovecot for IMAP. For spam filtering Rspamd does the job perfectly.

I personally use MDaemon which runs on windows Server and has a nice configuration ui. Have been using that for our small company for 20+ years.
