I can't send emails - this has happened before when Thuderbird is updated - in the past it eventually comes back - this time which has been several days - it still will not let me send - nothing has changed as far as my settings via my provider [Spectrum/Charter] - I have attached a screen shot of the error message I continually receive - please help

Here is the error message that spectrum was trying to get you to read: "The IP address you’re trying to connect from has an issue with the Domain Name System. Spectrum requires a full circle DNS for emails to be allowed through. Verify the IP you’re connecting from, and check the IP address to ensure a reverse DNS entry exists for the IP. If the IP address is a Spectrum-provided email address, contact us"
