gmail did push me to become self-hosted (currently a PI, but should become a risc-v mini-computer in the near future) because they broke noscript/basic (x)html browser support for re-authenticating my gmail account. It was years ago. Ofc, I did write my own smtp software (excrutiating simple), for the moment simple C (c89 with benign additions from c99/c11), but the target is 100% risc-v assembly with excrutiating simplicity. For now, I may not be one of their enslaved user anymore, but in interop with self-hosted smtp server, gmail is probably one the less worse out there: - they don't block (many smtp admin abuse of the broken and toxic spam-haus list by blocking instead of using grey-listing). - they have IPv6. - A few years ago it was fine to send them email with a pure IP smtp (yep, smtp was made to be able to work without the DNS mafia). But there is a catch: you end-up in their spam folder, DNS SPF and legit email exchanges doing nothing about it (DKIM is excessive overkill). Here, the real issue is non-tech-savvy people must be aware that legit emails WILL end-up in their spam folder: gmail should have such a warning right next to "spam name" like "spam(must be checked for legitimate emails)".
