      No, email has a very lenient specification that causes compatibility issues between different implementations. In addition to that, it assumes good intentions by all parties involved (because it was created when only universities and similar entities had email services), and all workarounds for this involve optional standards (DKIM etc) that aren’t always implemented or implemented properly.

        email has a very lenient specification that causes compatibility issues between different implementations.

        That is not a significant issue in the present day. I’ve run a Postfix server for over a decade and never had a compatibility problem sending or receiving email. I don’t use it much any more, because most other email servers will reject anything I send through it, but that’s a spam-filter problem, not a compatibility problem.

        Moreover, this isn’t the issue at hand. OP’s email is not being rejected because of a compatibility problem.

        In addition to that, it assumes good intentions by all parties involved

        How is that different from Mastodon? Anyone can sign up for a Mastodon account or self-host an instance. How, exactly, does Mastodon determine whether your intentions are good?

        all workarounds for this involve optional standards (DKIM etc) that aren’t always implemented or implemented properly.

        That, too, is not the issue at hand. OP’s email server has DKIM etc set up correctly, according to Google’s own tools.
