Mail Delivery Failed

[#1]

Please can someone help on why over the past few days I get a bounce back saying 'Mail Delivery Failed. This is a Permanent Error' type message. It's happened when sending to different email addresses and yes, I do have the correct addresses! I am connected to the internet. It's really frustrating!

If there is an attachment to the failure email that you can open, you may find that your problem is covered in this thread Hotmail rejecting mail from PN [Diagnostic-Code: s... - Plusnet Community.

As yet there is no solution although, as you will read (message #35), Plusnet are working on getting the servers removed from other providers' block lists.

How do I find message #35 ?
