cannot send email from Spectrum through Outlook

I am having the same problem as outlined in a post from 1/18/2025 with the same title that I've used here.  The rest of that initial post read as follows:

"I am unable to send email from my Spectrum rr.com email account through Xfinity network. Receive error code 1130. Task '[Edited: "Personal Information"]@nycap.rr.com - Sending' reported error (0x800CCC6F) : 'Your outgoing (SMTP) email server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider (ISP). The server responded: 554 p-impout006.msg.pkvw.co.charter.net cmsmtp [Edited: "Personal Information"]blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1130. "The server responded: 554 p-impout004.msg.pkvw.co.charter.net smsmtp [Edited: "Personal Information"]blocked" The IP address you're trying to connect from has an issue with the Domain Name System. Spectrum requires a full circle DNS for emails to be allowed through."

In the ensuing discussion, it was noted that "@XfinityAlex has been able to correct this for others."
