Examples and explanations of Java code sending messages (II.)

Prior to the use of a program in the mail-sending function, also wrote a related note, at that time using 163 mailboxes, after testing more than 163 accounts are feasible. But recently replaced the account with China Mobilechinamobilesz.com This end of time, but has been not connected to the server, verification does not pass, so had to re-made some changes, this period also refer to another colleague before the wording, successful implementation.
This implementation is similar to the previous one, just after testing, this way not only 163 of the mailbox is not a problem,China Mobile @chinamobilesz.com This is also possible, so it should be better than the one written in front,The specific code is as follows:
