Send Email over SSL

Download Chilkat Java Library

Java example code to establish an SMTP SSL connection to send email securely.

// Chilkat Java Example Program for Sending Email over SSL
	
// Connects to an SMTP server via SSL and sends mail.
// The default non-secure port for SMTP servers is 25.
// Usually, the SMTP SSL port is 465.  To send e-mail over
// SSL, it's as simple as setting two properties prior to sending:
	
// 1) Set the SmtpSsl property = true to indicate that you want SSL.
// 2) Set the SmtpPort property = 465

// Note: When sending email over an SSL connection, *everything* is protected.
// If authentication is required, your login/password is sent securely.  
// The entire email, including attachments, is sent over SSL.
