The SMPT server is timing out
"The message could not be sent because the connection to outgoing server smtp.gmail.com was lost in the middle of the transaction. Please try again."

that error is almost always the result of outgoing email scanning. Does you anti virus do this?

I dont think so. There is something with the SMTP settings which I cant figure out. I have gmail, I attach the file of the settings..
My gmail SMTP is on port 587. But I have not changed those settings in years.
The accepted setting is either STARTTLS security on port 587 or SSL/TLS on port 465.

Thanks, but I have already tried both and nothing....
It all started when I installed anew in a new computer. I think I'll try to copy the old settings from the old appdata...
...which I did and it works now. The settings are like you guys suggested so the problem is somewhere else, probably on the certificate part...
