Solved! Jump to the Best Answer.
The error message indicates that the service provider recipient of your email is unwilling to accept your email. The quoted reason is that your public IP address - the Internet address dynamically given to your broadband router when it makes a connection to the Internet - is on a spam blocklist.
You can try getting a different IP address for your router by disconnecting or depowering the router for a few minutes (30 minutes for fibre connections) then reconnecting or repowering.
But it's also important to use SSL/TLS encryption security and for the outgoing SMTP server to get network authentication as this helps to prevent other mail servers rejecting your messages.
