Email from spectrum business being bounced by google as residential

BrianinSocal

I have been running my own home mail for awhile. I use postfix and some outbound mails are not being accepted by Google. They falsely claim:

The IP you're using to send mail is not 550-5.7.1 authorized to send email directly to
    our servers. Please use the SMTP 550-5.7.1 relay at your service provider
    instead. Learn more at 550 5.7.1
    https://support.google.com/mail/?p=NotAuthorizedError

I bought business class to not deal with this. I really don't want to use a relay, allowing others into my email traffic.

I disabled ipv6 since they quoted my ipv6 ip in the error message; let's see if that helps.
