Your phrasing is a little off but I hear your frustration and sympathize with you. App Store creators say what cannot be installed, when it comes to third party apps. They generally don’t auto install things unless they make them OS components. Your phone’s network provider is the one loading apps you can’t uninstall, generally.




I also self host email and so far haven’t had any problems. Initial setup was annoying but it’s required zero effort this past few years, and I don’t think my emails land in spam folders. Maybe I can help?
Shoot me a message at test-message-lawrenceOfSuburbia@mspencer.net (which I’ll delete after it gets a message, for obvious reasons) and I’ll take a look. (I misspelled the name, I apologize, no insult intended)
Honestly I think I’ve received 10 spam messages in the last four years, and five have been from gmail addresses (Best Buy invoice spam) in the past two months. I submit each one to support.google.com/mail/contact/abuse and hopefully it helps.
