Humberto,
I'm not sure, but from googling around I see that "You may get this error
when you are trying to send an e-mail using gmail server in java."
Try making this change:
mail.extraproperties = mail.smtp.starttls.enable=true, \
mail.smtp.socketFactory.port=587, \
mail.smtp.socketFactory.fallback=false*, \*
* mail.smtp.ssl.trust=smtp.gmail.com
<http://smtp.gmail.com>*
I saw this suggestion here:
http://javainfinite.com/error-and-solution/javax-mail-messagingexception-could-not-convert-socket-to-tls/
Maybe it's not the gmail server but the mail server you are using, so
smtp.gmail.com might need to be *outlook.office365.com
<http://outlook.office365.com>*.
This is really just a guess.
Hope it helps.
-Jose
