The IP you're using to send mail is not authorized to send email directly to our servers.

Another issue in my ongoing war with gmail. Occasionally I get a reject message as shown below. It says to "use the SMTP relay at your service provider". I've tried using the Spectrum smtp.biz.rr.com relay. The problem with that is the authinfo credentials are for the Spectrum contract holder, and his email address isn't either for this domain (novatec-inc.com), or any of Spectrum's email domains. His email is outlook.com. Furthermore, when using Spectrum as a reply, Spectrum rejects the messages because the sender is not the specific contract holder's email. So, relaying through the Spectrum ISP won't work.
This problem is intermittent. I send to gmail recipients frequently without problem.
Note that this server does not use IPv6 for anything, including domain registration, so I don't know why the bounce message has the IPv6 address. 'host -6 2603:6011:2d02:ee82:f66d:4ff:fe5f:ffd1' returns nothing, so perhaps this IPv6 address is part of the problem.
Any idea how to fix this?
