Java implementation of 163 mailbox send mail to QQ mailbox success stories _java

Download and upload attachments, send text messages and send emails, are commonly used in the program functions, before recording the file upload and download and send text messages, due to the recent busy, the function of the mail to send no time to get, and now finally successfully 163 email to send mail to QQ mailbox, the following is the relevant code, A specific explanation can be referenced in the code:

  Based on the message's session properties to construct a message to send the sessions, where you need to note that the user name there can not be a suffix, otherwise it is not the user name//Also note that the password here is not the normal use of the mailbox login password, but the client generated another special authorization code

Note: I have a colleague to use this code to replace his account and client authorization code, a run on the error, and then reset the mailbox client authorization code, the error disappeared.

The above is the entire content of this article, I hope to learn Java program to help you.
