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: mail@address.com
rcpt to: rcpt@address.com
data
subject: test
test
.

Hello,

If esmtp support authentication username and Password it can be used for email delivery.

The sender-SMTP must ensure that the domain parameter in a HELO command is a valid principal host domain name for the client host.
