Using the PopSsl class

The PopSsl class provides an easy to use client interface for securely communicating with POP3 servers using SSL/TLS.  The PopSsl class provides both implicit and explicit SSL/TLS connections.  Implicit SSL/TLS connections are made by default using remote port 995.  Explicit SSL/TLS connections are made using an unencrypted connection to port 110 of a POP3 server and then switching to an encrypted mode using the STLS command prior to sending any additional data.

Example

The example below demonstrates connecting using implicit SSL/TLS on port 995

// create new PopSsl instance

PopSsl ssl = new PopSsl(hostname,995,username,password);

// establish SSL/TLS connection

ssl.connect();

// get messages and print subject

Enumeration e = ssl.getMessages();

while(e.hasMoreElements()) {

 EmailMessage msg = (EmailMessage)e.nextElement();

 System.out.println("Subject: " + msg.getSubject());

}

// disconnect

ssl.disconnect();                        

Example

The example below demonstrates connecting using explicit SSL/TLS and STLS command on port 110.

// create new PopSsl instance

PopSsl ssl = new PopSsl(hostname,110,username,password);

// set connection type

ssl.setConnectionType(PopSsl.STARTTLS);

// establish SSL/TLS connection

ssl.connect();

// get messages and print subject

Enumeration e = ssl.getMessages();

while(e.hasMoreElements()) {

 EmailMessage msg = (EmailMessage)e.nextElement();

 System.out.println("Subject: " + msg.getSubject());

}

// disconnect

ssl.disconnect();
