This morning when attempting to send messages from any email (I have a
number) to any address I get this error:
An error occurred while sending mail: The mail server sent an incorrect
greeting: Your IP address is on the XBL blacklist! Sending denied.

The messages into the sent box, but is not received.
Any ideas please? I am running under windows 10, both have been stable
for some time.
