Hello there mo.moster. We have read your message. We try to help you.

Oke you cannot send messages to recipients. Do you use a antivirus Software ? If so try to turn it of , can you send messages again? It could be the firewall in that program.

Go the configurations for outgoing mail settings.

Open Thunderbird. Select Tools, followed by Account Settings. In the Account Settings window, click on Outgoing Server (SMTP) .

Are you receiving error messages? You need to share those explicitly. Thank you.

Hello there again.

In the configuration of the outgoing Smtp settings, choose your account or identities name and click edit. you can see if ssl/Tls connection is checked. Make sure it is checked. And set the authentication password ,set it to normal. Check your port numbers if possible. Check if they are having a valid number. What are your port numbers at the moment?
