I have changed router to ZYXEL VMG3925-B10C . Old router was old and not cope with internet speed. however emails worked in and out OK. Since the change done yesterday when I try to send emails I get the following error message. Incoming emails are all received.

"Sending of the message failed. An error occurred while sending mail. The mail server responded: REJ-RELAY-001: relay not permitted. Please check the message recipient"

The error comes somewhere in the domain of Thunderbird , router or internet provider but as as I am not an expert I do not how to solve the problem.

Recheck settings for incoming server and SMTP server to ensure they're for the same account. That would be my first thing to check.
