What is POP before SMTP?
POP before SMTP utilizes authentication with POP3 that is performed at the time of receiving e-mail.
SMTP permits the sending of e-mail from the authenticated IP address for a limited time.
Since authentication is disabled after a specific time has elapsed, authentication with POP3 will be
required again.
* In the case of authentication with POP3, a password is sent in clear text. POP before SMTP using
APOP is also available. With APOP, a password is sent in encrypted form.
The V8 series, however, supports POP3 only.
What is SMTP Authentication?
Authentication is performed with the SMTP server.
SMTP Authentication is classified into several authentication methods.
The V8 series supports LOGIN, PLAIN, CRAM-MD5, and DIGEST-MD5.
Since the SMTP server automatically performs authentication according to the available method, users
are not requested to make configurations.

About the authentication methods
• PLAIN
This method sends user names/passwords in clear text (not in encrypted form).
• LOGIN
LOGIN is similar to PLAIN. But it often sends information, as performed with POP3, in divided
forms, such as USER xxxxx or PASS xxxxxx. Because the standard specifications of LOGIN are
not established, there are e-mail servers that use LOGIN in their own way.
