Email send problem PC MS Outlook from .nc.rr.com email
I have newly installed ATT fiber; prior was Spectrum cable; no problems with ATT Internet - speed/connectivity spot-on
I use @nc.rr.com email - owned by Spectrum
Prior to getting ATT Internet I had no problems SENDING email from PC Outlook 2010 client and I could receive also
Now connected to ATT I cannot SEND (but can still receive) email
Same issue on iPhone 11 sending from @nc.rr.com mail acct
However, if I disable WiFi on iPhone and try via cellular data I have no problem
I have tried both POP3/SMTP and IMAP/SMTP Outlook client - no difference
Error reported by Outlook:
Task '[email scrubbed] - Sending' reported error (0x800CCC6F) : 'Your outgoing (SMTP) e-mail 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-impout002.msg.pkvw.co.charter.net cmsmtp 68.89.xx.yy blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1130'
Note: 68.89.xx.yy is my public ATT IP
The Spectrum email-error-code site says error AUP#Out-1130 is:
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.
So far contacting Spectrum and ATT has resulted in a finger pointing circle of 2
Anyone have an idea how to resolve this?
