It shows that the email verification fails. You have to find what is written in Transport.java:218, SendMail.java:185, what to do, and to find the cause of the error according to the operation performed.

Transport.java is a class under the javax.mail package, not what I wrote
SendMail.java:185 line is mail.sendMails (email, content);
I did not find anything wrong
