MIME – Multipurpose Internet Mail Extensions (MIME) provides the voice
messaging system the capability to read e-mail message header and
body information.
Multipart MIME messages enable the e-mail system to send enhanced
versions of the message for messaging clients such as Lotus
Microsoft Outlook. Multipart MIME messages contain plain text messages
that can be read to subscribers over the phone.
POP3 – Post Office Protocol and Authenticated Post Office Protocol.
POP3 is a standard internet protocol used for retrieving Internet e-mail
and is used by the e-mail client to communicate with SMTP mail servers.
With POP3 the user name and password are sent across the network in
clear text. With APOP, the password is encrypted before being transmitted
over the network to the SMTP mail server.
SMTP – Simple Mail Transport Protocol (SMTP) provides the voice
messaging system the capability to send outgoing e-mail messages. The
system forwards voice mail and faxes to the e-mail system, receives e-
mail notification of new fax/voice mail, and uses voice mail features to
reply to e-mail messages. SMTP can be configured to restrict the type of
messages sent such as only allowing SMTP mail to be sent to other users
on the same domain.

Subscriber E-mail Authentication Protocols

PLAIN – PLAIN is a simple clear text password mechanism. The
mechanism uses a user name and password to authenticate users.
NTLM – NTLM is a challenge-response authentication protocol. The
server authenticates the client by sending an 8-byte random number, the
challenge. The client performs an operation involving the challenge and a
secret shared between client and server, e.g. a password. The client
returns the 24-byte result of the computation. In fact, in NTLMv1 two
computations are made using two different shared secrets and two
24-byte results are returned. The server verifies that the client has
computed the correct result, and from this infers possession of the secret,
and hence the identity of the client.
LOGIN – The LOGIN mechanism is a non-standard mechanism, and is
similar to the PLAIN mechanism except that LOGIN lacks the support for
authorization identities.
