Thunderbird: need to reboot PC every now and then.
I'm using latest Thunderbird version set with IMAP on W10. It works fine and the PC is on 24x7. Every now and then Thunderbird stops sending Mail claiming it cannot contact the SMTP Server but the Server is correct and it works fine. I have to reboot the PC in order to make it capable of sending Mails again. CPU, RAM, SSD and Net values are almost Idle. I'd like to identify what causes this issue. I've checked the Windows Application Log but there's anything that helps. Where can I start troubleshooting from? Thanks.

Please see the attached PIC. The SERVER is fine and after I rebooted the PC, I could send the Mail.

Timing out on an SMTP server is indicative of a problem with Third Party Anti-Virus software - especially Bitdefender.
If you search for the string "the connection to the outgoing server SMTP timed out" in the top right search field, there will be numerous articles with information about how to resolve this issue.
The most common solution is that Anti-Virus software needs to be switched off from scanning emails.
If the solutions offered don't work, please reply to the post and it will be relisted as in need of a solution.
A 'test' is to start Windows in Safe Mode with Networking to see if the problem persists but it does appear from your post that the occurrence is intermittent.
Hi, I use ESET ENDPOINT ANTIVIRUS. The next time it happens I can either suspend ESET's protection (which is generic) or ESET's Mail Client protection (which is specific). I'll report back. Thank you.

There are a lot of people who come on the Forum with the same sort of problem. They have decided against using the free, inbuilt Windows Security Suite in Windows and opt for Third Party Anti-Virus Software - which then causes a raft of error messages that aren't obvious are being caused by it.
I have never seen a problem with the Windows Security Suite. At least, not yet. Unfortunately, I can only point you to the likely solution - I have no experience of altering Third Party AV to allow TB to do its job.
Hope the solution works.
