After years of successfully using thunderbird, it stopped sending and recieving on my desktop computer. Emails still work fine on my phone and webmail and on my laptop running Thunderbird. I've reinstalled thunderbird and I've even copied the profile from the laptop (which works fine) onto the desktop. Both running 52.5.2 (32-bit) with identical profiles.

When I hit send it says connected to my server, but after a while I get a popup saying: 

An error occurred while sending mail: The mail server sent an incorrect greeting:  Cannot connect to SMTP server 2403:2f00:f002:401::6000:23a (2403:2f00:f002:401::6000:23a:587), connect error 10060.

I then get another saying there was an error saving the message to.retry?

that looks like it might be an IPv6 IP address. So just a guess, but unless you are specifying the server in your settings by an IP address it may well be our anti virus is having an issue. Try turning it off and see if things change.

Thanks Matt. I disabled Avast antivirus and TB now works. But I guess the next problem is how do I fix this with Avast still running/

start be trying it without email scanning. or the firewall component. That will narrow the cause further.

Thanks once again for the reply Matt. I disabled "mail shield" in Avast and it worked. So then I enabled it again and went through the list of mail shield components. Disabling SSL scanning as in the screenshot works, so I have it narrowed down to that. Is it safe to leave SSL scanning turned off? Or do I need to do something else?
