Unable to email anyone from my primary domain name; thanks Google Mail and G Suite.

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 at gmail.com) would help you get them delivered to your INBOX.

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.

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.
