如何使用Java（而非Javamail）连接到电子邮件

Question

Is there a way to connect to your email inbox in java (using netbeans IDE) without the use of JavaMail API? I have been searching for a way to do it without the use of that API as I am trying to construct a program which reads my email and stores them into a database using sql server. is there a way?

Answer 1

You can use Socket classes. Send message directly.

Answer 2

Why not use JavaMail? There are other libraries available, such as ChilKat's - or you could talk POP3/IMAP directly, you know open a socket on port 110/143 and issue commands and read the responses (which is what the libraries will do for you).

If you have to provide a single JAR file, you can merge the JavaMail classes (and dependencies) with your own code, or - depending on your target infrastructure - a WAR or EAR might be more appropriate.

Cheers,

Answer 3

If you want to do this the hard way, you can write eg a POP3 client in Java yourself. Use Socket, connect to the right host and port (port is usually 110) and start issuing POP3 commands.
