Not really Gmail's fault, either.  Someone above said they had the
same problem with Comcast.net.

Gmail complies with the relevant RFCs just fine. It's most likely
simply because most people who use email, use Gmail.

In addition, gmail properly implement SPF and DMARC checking.

There's over 1 billion gmail account as of 2016, so that's why most
people who are bouncing would be gmail.
