I’m trying to de-Google my life and self-host more. One tricky point with me is calendaring. I can get a CalDav server running and syncing with my Android phone without much hassle, but I haven’t yet found a server or client that can send e-mail reminders for events, rather than just pop-up notifications.
I’ve been told to try Nextcloud. I tried installing it but it’s overkill for me, and I don’t want to deal with setting up a domain. Surely there can’t be exactly one CalDav option that can send email reminders. But I’ve never heard anyone say anything other than “Nextcloud.”
Counterpoint: if you system is configured such that the mere act of trying to send an email results in serious delays and regular bounces, you’re doing email wrong. Even push notifications may require third party routing through Google, Apple, or similar to get to the core OS in some cases.
Yes, I recognize that hosting an SMTP server is difficult these days and can’t always be done at home due to IP restrictions. But that doesn’t mean you have to have an email server at home. I have a third party email on my domain and I can dispatch SMTP which arrives at expected non-delayed times even to Google and Microsoft accounts.
I honestly wish more software would simply speak to an SMTP server of choice rather than defaulting to just hitting the CLI mail send or attempting a direct SMTP connection.
