Test

Test with the Main method

public static void Main (string[] args {  
        mail mail = new Mail ();   
        New Mailutil (). Send (mail);  

Results:

errors encountered during

Midway encountered a org.apache.commons.mail.EmailException:Sending the email to the following server failed:smtp.163.com:25 error.

The internet looked up the error. Reason: The port is wrong, sendemail.sethostname ("smtp.163.com"); is not open authentication, is the password (authorization code) wrong

I used the password to use the mailbox login password, so reported the wrong, should use authorization code.
