Can receive Emails successfully but cannot Send Emails. Error message reads as follows-: mf-505: Sender Policy - Relay denied. Please verify that your Email address is correct in your Account settings and try again. I have verified that my Email address is correct in Account Settings but this does not correct the problem. Can you help? Michael

Check your Ougoing (SMTP) Server Settings. Is the username there the same as the email address from which you're trying to send the message? Your SMTP server may require both to be the same.

Another possibility is you're using a VPN and the SMTP server doesn't accept sending mail from the IP address your VPN is making you seem to have. In that case, check whether your VPN has an option called split tunneling which would allow you to let Thunderbird bypass the VPN. Otherwise, you'll have to disable the VPN to be able to send with that SMTP server.
