Lately, I have been receiving error message "Sending of the message failed. The message could not be sent because the connection to Outgoing Server (SMTP) mail.iinet.net.au timed out. Try again." I have checked the settings and they are correct. The message will send using iinet webmail, but not with Thunderbird, so the problem appears to be with Thunderbird. These are usually emails with an attachment (even small). The sending of the email stalls aroung 35%, before the message appears. I am using version 102.13.0 (64 bit). I am using Windows 10 with ESET Security. Tried sending with without ESET protection which made no difference. Can you please help?

Try to start Windows 10 in safe mode with networking enabled. Does the problem go away?

Windows safe mode disables anti-virus software. This is a troubleshooting step, not a solution.

Beyond that, see https://support.mozilla.org/kb/cannot-send-messages
