Session. If you get the session, it indicates that you have connected to the mail server, after completing the first step, the Connection is established, and its function is similar to that of JDBC Connection.How can we get the Session?
By checking the j2ee document, we can find two methods: 1. session. getInstance (Properties prop); 2. session. getInstance (Properties prop, Authenticator auth);, this method returns a Session, but requires two parame

It uses the timer management mechanism, retransmission mechanism, and backup server mechanism to ensure that the interactive messages betwee
I saw the email development video explained by Zhang Xiaoxiang, but I only watched a small part of it. At that time, I was a little newbie and didn't understand it. I thought it was a very complicated technology. The mail sending function is used in a small project that has recently been practiced. This function is implemented by referring to the Code on the Internet. Now, it's so easy!
Before enabling this function, you need to download the jar package mail. Jar required for sending emails. Yo
Used to think that JavaMail is a very tall thing, so on the Internet to find the knowledge about JavaMail, in fact, did not think so tall, I just learned to send the mail part, then I would like to paste the code I wrote, specific implementation code has a detailed explanationThe first is to send a regular message//Send regular mail Public Static voidSendtextmail ()throwsmessagingexception {//first step.

projections cannot contradict each other (if P is safe, non-p is definitely unsafe). Therefore, it is possible to reach a consensus if the node is not able to reach an irreconcilable state according to the behavior of the estimator. Furthermore, once a node sees a proposition that is safe, it knows that the final publicity results will remain correct.2.

directory for each user who uses this messaging system for a long time occupies a lot of space. This will directly cause a spike in disk space on the mail server.4.mime:mime is not a protocol for sending messages, it defines the format of the message content as an extension of a multipurpose message: The format of the message, the format of the attachment, and so on. Some RFC standards involve MIME:RFC 822, RFC 2045, RFC 2046, RFC 2047, and interested matrixer can read about it. As developers o
Introduction to the Java Mail delivery function implementation1, Java Mail Introduction:Java Mail is the use of existing mail accounts to send mail tools, for example, I registered an email account in NetEase, through the control of Java mail, I can not personally login NetEase mailbox, let the program automatically use NetEase mailbox to send mail. This mechanism is widely used in such aspects as registration activation and the sending of spam messages.2. Configure the JavaMail development envi
, which is inefficient for sending multiple emails on the same mail server.Note: If you need to monitor the MAIL command during mail sending, you can set the debug flag before sending:Session. setdebug (true ).
G. Store and folderConnectSession is used for receiving and sending emails. However, after obtaining the session, we need to obtain a specific type of store from the session, and then connectStore, where store represents the mail server that stores emails. The user name, password, or

user information, billing information, and other information. User information is added to the database by the network administrator. The billing information is from the RADIUS server. Other information includes log information.
2.2 RADIUS packet structure
RADIUS is the protocol at the application layer. In the transport layer, its packets are encapsulated in UDP packets and then encapsulated into the IP packet. Port 1812 is used for RADIUS Authentication, and port 1813 is used for billing.
