For at least a few years we configured SSL for conecting to GMail server in this way:

SSLIOHandlerSMTP.Versions := [sbTLS1,sbTLS11,sbTLS12];
SMTP.UseTLS := utUseExplicitTLS;

And it worked fine. At last friday (24/6/2016) we started getting reports from our customers becasuse GMail started to fail (SSL not available on this server).

Trying to fix the problem we removed the first line of this code, making the component to work with it´s defaults, and problem disapeared.

Maybe somebody know what changed at GMail ...

Best regards,

I can only guess, but maybe they don't like TLS 1 - it has been recommended for fading out.

I really don´t know what changed. I simply left to default values which is:


... and it works now. Maybe, there is a problem at runtime, when setting the value to field "Version".

Best regards.
