I am having problems sending email to some external servers. I get the error message that the SMTP server timed out. Most mail sends OK though, and yesterday I was able to exchange a couple of emails with a person before Thunderbird decided to stop sending my mail to them. I can solve this by going on our webmail and sending the message there, so this seems to be a Thunderbird problem.

I am at the University of Iceland so they are my provider (reiknistofnun.hi.is) and my ISP. I am using Windows 7 Enterprise. My Windows 7 firewall is on. I have a McAFee virus protection installed, but I don't think it is enabled (see attached). I am using Thunderbird 45.3.0, but I have encountered the same problem with previous versions.

Thanks for your help!

Try with Windows in Safe Mode with Networking. That should disable McAfee altogether. AV scanning your outgoing would be my first suspicion.
