When I open Thunderbird I get "sending of message failed" error messages due to server timeout, even though I didn't attempt to send anything.
When I open Thunderbird I get two messages indicating sending of message failed due to SMTP server connection timeout. I HADN'T TRIED TO SEND ANYTHING! What is T'bird trying to send as soon as I open it? I have nothing held in the Outbox, and only one unfinished mail in Drafts.

About Thunderbird

Thunderbird is not using any proxy to send mail through an antivirus application.
Check for the latest version of Thunderbird update or update to the latest version.
Download any network monitoring or analysis tool like Wireshark, NetworkMiner etc. to test network traffic before sending outgoing messages.

Switch off your antivirus or Windows firewall and try sending the mail again. If Thunderbird was blocked by them, then it will work. Re-check the server or SMTP port connection and assigned right port if it is not set. OR change the Thunderbird SMTP server port and check TLS/SSL server setting.

For POP
Informing: Host name: pop3.domain

Thank you for your information. However this does not solve the problem. This did not happen until I upgraded to T'bird ver. 60.9.1 a week or two ago. I have been using the same POP configuration and antivirus settings for many years with no problem. My question is, what is T'bird trying to send? I am not actively sending ANYTHING; I merely opened Thunderbird to read my mail, NOT send anything! All incoming and outgoing emails work fine, despite the failure message. Since send and recv both work OK I can ignore the messages. I just don't want T'bird taking it upon itself to send something that I DID'T SEND.
Hello there Bmbran..
It looks like if you have used everything that I have sent you does not help or functions as you would like .Then I would delete the relevant piece of software.Again reinstall Thunderbird , install your antivirus program to check. Delete all odd software from your computermachine with a good program cleaner/deletesoftware.
