LinuxQuestions.org - Make sendmail require authentication

Hello,

I am running sendmail and can send e-mail fine at the moment. What I would like to do is force sendmail to require authentication.

I created a user name and password using salspasswd and when I send the mail using that user name and password (via Java) it works fine and sure enough if I typo on the password the mail does not get sent. Great.

But, when I set the system property for mail.smtp.auth to false:

Code:

System.getProperties().put("mail.smtp.auth", "false");

I can send email with any user name and password.

How do I make sendmail require authentication?

Thanks!

Tim
