OpenJDK 27 · sun.net.smtp.SmtpClient · APIdia, the JavaDoc alternative

This class implements the SMTP client. You can send a piece of mail by creating a new SmtpClient, calling the "to" method to add destinations, calling "from" to name the sender, calling startMessage to return a stream to which you write the message (with RFC733 headers) and then you finally close the Smtp Client.
