Our messaging team enforced TLSv1.2 protocol now and so we are not able to send mails. It's throwing "** Caught javax.mail.MessagingException, Can't send command to SMTP host" error. Could some one please help me out of this? Please let me know if you need some more info on this. Thanks in advance.
