I can receive emails but not send them. I get this error message: "An error occurred while sending mail: The mail server sent an incorrect greeting: cm12gb1 smtp.talktalk.net ESMTP server not available." My email provider has not been able to help me. I had a similar problem, albeit with a different error message requesting a server password, two weeks ago but was able to solve it by changing the Server settings in Thunderbird. However, this time there don't appear to be any changes that I can make that will resolve it.

Thank you. I did contact TalkTalk again and this time got through to a very helpful support person. First of all he directed me here: https://help2.talktalk.co.uk/configuring-mozilla-thunderbird-talktalk-email . However, that was not the end of the matter as there were some specific settings for @lineone.net mail accounts. After about 30 mins on the phone we got the problem solved between us. Or I hope that its solved. I still don't know how or why the settings were changed a few weeks ago from those that had worked perfectly well for the previous 10 months. Anyway, now happily sending emails from my desktop again and, incidentally, have solved a problem with sending emails from my phone at the same time by adjusting those settings too.

Apparently the error is from your provider's server. Talk to your email provider.

I have already tried that but haven't been able to get any help from them.

Ask for someone there that knows more than to answer the phone when it makes a noise.
