I use my own personal domain name for various UNIX stuff, including sending log-related things to myself out of cron, which end up in my own Gmail.com account, either directly, or through forwarding (w/o SRS).

Too bad you don't use G Suite as it allows you to notate incoming relays where Gmail does not. It is possible that authenticating (logging in as you@gmail.com) would help you get them delivered to your INBOX.
A couple of months ago, I setup some new scripts that would send me new nightly emails. It's all plain text, but had a few dozen of domain names present (it's logs). Absolutely no links, just plenty of domains which I don't control. So, Gmail has been presenting most of these messages with their red warning label that the email contains malicious links, even though all of these emails contained zero links, zero URLs to any of these unknown domain names, zero URL schemes, zero "http://", zero "https://" etc. You get the idea.
Many an MUA would convert the anything.knowntld (and other) strings (some don't even check for known TLDs) into clickable links if no adjacent URL was present so it seems that so far as Gmail is concerned those strings are something you might eventually be able to click thus they are URLs.
Since about a few weeks ago, I am now seeing at least a 95% rejection rate for my domain name, for ALL email, including the forwards.
My experience says that: their system has learned that your system(s) continued to send messages that their user (yes you, but they don't know that) did not want, i.e., you left it marked as SPAM or deleted it without reading the message, or at least not enough was noted as not SPAM *and* read (aka displayed, and not for half a second either) so as to influence their AI, which makes mistakes and will never correct them if not fed correcting info. /mark
