https://community.plus.net/t5/Email/Internittent-email-failure/m-p/2055590#M62025 <P>Emails to outlook and hotmail e-addresses have often been returned to me with the message "... could not be delivered due to a permanent error ...". Sometimes the problem disappears after a few days/sometimes it doesn't. Now sending emails to talktalk is going the same way. What is the issue? Can Plusnet fix it? Does the Greenby migration sort it? Thanks all.&nbsp; &nbsp;Peter</P> Fri, 14 Aug 2026 16:14:13 GMT Prtplus1 2026-08-14T16:14:13Z https://community.plus.net/t5/Email/Internittent-email-failure/m-p/2055590#M62025 <P>Emails to outlook and hotmail e-addresses have often been returned to me with the message "... could not be delivered due to a permanent error ...".
