Question

I am using Javamail api and gmail smtp server to send mail in java without giving password. I have using the below code. here i am using javax.mail jar file

     Properties props= new Properties();

     props.put("mail.smtp.host", "smtp.gmail.com");
     props.put("mail.smtp.port", 587);
     props.put("mail.transport.protocal", "smtps");
     //Put below to false, if no https is needed
     props.put("mail.smtp.STARTTLS.enable", "false");
     props.put("mail.smtp.auth", "false");

     Session session = Session.getInstance(props);

I am getting the below error

      Must issue a STARTTLS command first. b4sm3005855pdh.2 - gsmtp

Is there any wrong in implementing the code? is it posssible to implement without password ? pls any one help me on this

You've also misspelt "protocol".

First, the name of the property is "mail.smtp.starttls.enable".

Second, no, you can't send mail through Gmail without authenticating first, e.g., using your password.
