Can ESMTP be used for email delivery? I am trying to configure our own email server with PRTG. Using Telnet I am able to send emails using following commands but when I configure same settings in PRTG it says unsuccessful authentication. I think the problem is with HELO Ident. Am I right?
EHLO servername auth plain [authstring] mail from: [email protected] rcpt to: [email protected] data subject: test test .
