I am using Finalbuilder 126.96.36.19965 on Windows 10 and no matter what I tried, I couldn’t get the SMTP action to work against our E-mail server using SSL, I got all sorts of errors indicating that TLS negotiation failed.
Knowing that Finalbuilder was developed using an Embarcadero compiler, and knowing that some of the Delphi components I use myself are picky about which version of the OpenSSL libraries to use, I did a little experiment and replaced your version of ssleay32.dll (dll version 188.8.131.52, product version 1.0.2u) with a slightly older version which I had on my hard drive (dll version 184.108.40.206, product version 1.0.2n)
And much to my surprise, sending mails through SMTP using SSL works perfectly now .
So I suspect that Finalbuilder comes bundled with a version of this DLL that is not supported by your SMTP component.
If that was the case then we would have had thousands of bug reports by now - from ourselves too since we also use this action.
On the SMTP tab there is an option, Log SSL Negotiation, try turning on that and show us what it produces. The most likely cause is the client and the server not agreeing on common cyphers - which mail server are you using?
