What is SMTP?
Simple mail transfer protocol (SMTP) is a set of rules that define the interaction between
programs that send and receive e-mail. In order for the MFP to send documents to e-mail, it
must be connected to a LAN that has a valid SMTP IP address. The SMTP server must also
have Internet access.
If you are using a LAN connection, contact your system administrator to obtain the IP
address for your SMTP server. If you are connecting through a DSL connection, contact the
service provider to obtain the SMTP server IP address.
What is LDAP?
Lightweight Directory Access Protocol (LDAP) is used to gain access to a database of
information. When the MFP uses LDAP, it searches a global list of e-mail addresses. As you
begin to type the e-mail address, LDAP uses an auto-complete feature that supplies a list of
e-mail addresses that match the characters you type. As you type additional characters, the
list of matching e-mail addresses becomes smaller.
The MFP supports LDAP, but a connection to an LDAP server is not required in order for the
MFP to be able to send to e-mail.
