My outbound email stopped connecting

My outbound email stopped connecting on both my laptop (Outlook client) and on my iPhone (Mail client) earlier this week.

I have confirmed all settings are correct, including port numbers and URLs. I have changed nothing - they simply stopped sending. Receiving works.

Error from Outlook is this:

Task '[email protected] - 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-impout007.msg.pkvw.co.charter.net cmsmtp 4.2.165.35 blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1130'

    Hello @MaineAddress and welcome to our community!

    Are you using the Spectrum SMTP servers to send your mail? It looks like according to the error message provided you might be connecting from an IP address that is not a Spectrum IP address. I looked up the AUP# provided and it means the following:

    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. Verify the IP you’re connecting from, and check the IP address to ensure a reverse DNS entry exists for the IP. If the IP address is a Spectrum-provided email address, contact us.

    Are you able to connect and send mail using webmail.spectrum.net?
