We are trying to encrypt the email which our application is sending . We have added mail.smtp.starttls.enable="true" in the root.xml and in the SMTP host , we are using postfix server and there we have added smtp_tls_security_level = encrypt in the main.cf file.
When our application is sending email , we are getting the below error
So we searched and found the option smtpd_tls_cert_file = none , which we added in the main.cf file. Now we are seeing it is initiating the TLS connection however getting the below error
smtp-zbc-xx01 - is the SMTP server where postfix is running.We are using 25 port.
abc.dd.com - is my tomcat server where java application is running which is sending the email via smtp-zbc-xx01 server.
Any help in this issue will be highly appriciated.
