Can't send, get error message 5.7.1
Here is the complete message:
An error occurred while sending mail. The mail server responded: 5.7.1 [address] Relay access denied. Please check the message recipient [address] and try again
Using Outlook with same server settings, messages go through. If I resend multiple times from Thunderbird the message goes through. If I move the message to draft, and then check the isp's webmail, the message has been received by my isp and is in the proper webmail draft folder. Last night I had the same issues on my home computer (I'm currently at work).

The 'Relay access denied' error indicates your email provider is different to your ISP.
Can you post your Troubleshooting Information?
