______Server Error: 550__Server Response: 550 Invalid recipient address____

"The message could not be sent. The setting for your outgoing email [SMTP] server might need to be configured. To find the server settings for 'tricia/*** Email address is removed for privacy ***', please contact your email service provider.

Subject 'announcement'
Server Error: 550
Server Response: 550 Invalid recipient address
Server: 'smtp.blueyonder.co.uk'
Windows Live Mail Error ID: 0x800CCC79
Protocol: SMTP
Port: 25
Secure(SSL): No"

The email address on the error notice is now not in use, although I was not sure at the time I sent the original message. Now the error message keeps occurring and I cannot find a way of deleting it for ever.

Answer

Your server may need authentification, try this:-

 

Open your mail server, click on the problem account, (if it didn't load automatically). Click 'Properties' and click on the 'servers' tab. Check the 'Log on using authenticated POP (APOP)' and then click 'settings'. In the 'settings section check the 'use same settings as my incoming server' then check 'my server requires authentification'. Click 'apply'.
