Simple Mail Transfer Protocol (Smtp); Post Office Protocol (Pop) Version 3 Server - IBM i series Handbook

TCP/IP Connectivity Utilities (5722-TC1)
LDAP Directories Support – New with V5R1
New support is added to allow information about iSeries printers and NetServer print shares
to be published into LDAP directories. This allows the user to write applications that query the
LDAP directory for iSeries printer information such as a printer's location or capabilities. It
also allows the user to configure iSeries printers directly on their Windows 2000 desktop by
using the Add Printer wizard available in Windows 2000 and specifying that the information
necessary to publish the printer be obtained from the Windows 2000 Active Directory.

Simple Mail Transfer Protocol (SMTP)

Simple Mail Transfer Protocol is used to send or receive electronic mail. For consistency with
other iSeries mail functions, SMTP interoperates with Systems Network Architecture (SNA)
Distribution Services (SNADS) through AnyMail/400. SNADS and AnyMail/400 are part of
OS/400.
SMTP supports mail objects up to 2 GB, SMTP distribution, MIME, optional automatic
enrollment of senders of incoming mail, in the system distribution directory and alias tables,
OfficeVision for AS/400 notes, messages and attachments. You can tune SMTP depending
on the mail load on your system, therefore enabling greater scalability.
New option to enable journaling for mail delivery status tracking and mail statistics. Like
TELNET and FTP, SMTP supports both client and server functions on iSeries. It can serve as
a mail gateway to Interconnect SNADS, and TCP/IP SMTP electronic mail networks.
iSeries SMTP is enhanced with the following features:
• Increased simultaneous connection support. iSeries SMTP is no longer restricted to a
maximum of 16 inbound and 16 outbound simultaneous mail connections. You can
tune SMTP depending on the mail load on your system, and therefore, enable greater
scalability.
• Enhanced domain name system resolver support. The iSeries SMTP client processes
all mail exchanger (MX) records returned by a domain name server query. This means
that there is less undeliverable mail when sending to large Internet Service Providers.
• New option to enable journaling for mail delivery status tracking and mail statistics.
• New option to require all mail received by iSeries SMTP to be processed by the iSeries
Mail Services Framework (MSF) to improve security.
• Enhancements for the automated retry of mail when dial-up connections are
established and finer granularity of mail delivery retry timing.

Post Office Protocol (POP) Version 3 Server

The Post Office Protocol (POP) Server is the iSeries implementation of the POP3 mail server.
This server enables iSeries to act as a POP server for any client that supports the POP mail
