Here is my code using which I am trying to connect to mail server to read mails using Java.

Properties props = new Properties();
props.put("mail.imap.port", "25");
Session session = Session.getDefaultInstance(props, null);
Store store = session.getStore("imap");
store.connect(ServerIP, "cma", "C0rnh0le$8");

When system tries to compile the line store.connect(ServerIP, "cma", "C0rnh0le$8"); it generates the above mentioned exception, I found this and this on StackOverflow, but not get any help after adding that jar.

Define Protocol

SMTP - is the protocol to send email

POP3 - is the protocol to receive emails

IMAP- IMAP is an acronym for Internet Message Access Protocol. Its an advanced protocol for receiving messages.

Solution

  • The default IMAP port is 143. You are using the default SMTP port, 25. That should fix your problem, assuming the host/username/password are correct!

    Cheers, and happy coding.
