View Mail Information List

The following is the Java code for viewing the mail Information List:

Import javax. Mail. store;
Import javax. Mail. fetchprofile;
Import java. util. properties;
Import javax. Mail. Session;
Import javax. Mail. folder;
Import javax. Mail. message;
Import javax. Mail. Internet. internetaddress;

Public class semail {
Public static void main (string [] ARGs ){
Try {

Properties props = new properties ();
Session S = session. getinstance (props );
Store store = S. getstore ("POP3 ");
Store. Connect ("pop.163.com", "bluebit_cn", "xiaohao ");

Folder folder = store. getfolder ("inbox ");
Folder. Open (Folder. read_write );

Fetchprofile profile = new fetchprofile ();
Profile. Add (fetchprofile. item. envelope );
Message arraymessage [] = folder. getmessages ();
Folder. Fetch (arraymessage, profile );

System. Out. println ("Number of inbox Emails:" + arraymessage. Length );
For (INT I = 0; I <arraymessage. length; I ++ ){
// Email sender
String from = arraymessage [I]. getfrom () [0]. tostring ();
Internetaddress IA = new internetaddress (from );
System. Out. println ("from:" + ia. getpersonal () + '(' +
IA. getaddress () + ')');
// Mail title
System. Out. println ("title:" + arraymessage [I]. getsubject ());
// Mail size
System. Out. println ("Size:" + arraymessage [I]. getsize ());
// Email sending time
System. Out. println ("Date:" + arraymessage [I]. getsentdate ());
}

Folder. Close (false );
Store. Close ();
} Catch (exception ee ){
Ee. printstacktrace ();
}
}
}

Answer

The basic process of deleting a message is to call setflag () on the message and set the flags. Flag. Deleted flag to true.

Message. setflag (flags. Flag. Deleted, true );

Then, when you close the folder, deleted messages will be removed.

Be sure to open the folder for read/write access:

Folder. Open (Folder. read_write );

The following program demonstrates listing each message in the folder and prompting for deletion:

Import java. Io .*;
Import javax. Mail .*;
Import javax. Mail. Internet .*;

Public class deletemessageexample {
Public static void main (string ARGs []) throws exception {
String host = ARGs [0];
String username = ARGs [1];
String Password = ARGs [2];

// Get session
Session session = session. getinstance (
System. getproperties (), null );

// Get the store
Store store = session. getstore ("POP3 ");
Store. Connect (host, username, password );

// Get folder
Folder folder = store. getfolder ("inbox ");
Folder. Open (Folder. read_write );

Bufferedreader reader = new bufferedreader (
New inputstreamreader (system. In ));

// Get directory
Message message [] = folder. getmessages ();
For (INT I = 0, n = message. length; I <n; I ++ ){
System. Out. println (I + ":" + message [I]. getfrom () [0]
+ "\ T" + message [I]. getsubject ());

System. Out. println ("Do you want to delete message? [Yes to delete] ");
String line = reader. Readline ();
// Mark as deleted if appropriate
If ("yes". Equals (line )){
Message [I]. setflag (flags. Flag. Deleted, true );
}
}

// Close connection
Folder. Close (true );
Store. Close ();
}
}
