I noticed that your notification emails (in this case for runs to verify and runs being beaten) all go to my spam folder, because they're matching the SpamAssassin rule "BOGUS_MIME_VERSION Mime version header is bogus". The MIME version header is "MIME-Version: 1.0;". I'm guessing the semicolon at the end might be the issue, e.g. Wikipedia says it's just "MIME-Version: 1.0" (https://en.wikipedia.org/wiki/MIME).
My mail server is also saying that your DKIM signatures are invalid, not entirely sure if that issue is on my side, but it would probably make sense to run your emails through an email tester once in a while.

@mooware, I would submit a Support ticket reporting this.
However, I'm not sure if @Meta has reviewed any of these recently. Since I have a bug report ticket that's been pending for 3 months lol
