OK, I think I have found the issue. The constants for ssl protocols differ for 
smtp (startTLS) and smtps. 

You have to find the string "mail.smtp.ssl.protocols" in 
src/protocol/org/apache/jmeter/protocol/smtp/sampler/protocol/SendMailCommand.java
 amd replace it with "mail."+protocol+".ssl.protocols".

I had tested Port 25 with startTLS and you are using smtps, so it worked for me 
and didn't work for you. 

Please try it out.
