Configuration & Vendor Links

Before you start, unzip the .zip file in the C:\SM_TEMP\ directory.

From Program Manager, choose Run from the File menu.

If you are installing from an unzipped installation file, type the path of the temporary working directory where you unzipped the Sendmail installation program, followed by SETUP.EXE, as in the following example:

If you have Sendmail on CD-ROM, enter the drive of the CD-ROM followed by SETUP.EXE. For example:

Follow the instructions as they appear on your screen.

The Registration screen displays.

Enter registration information (name, company, serial number).

Sendmail Setup continues.

Enter the mail domain name for which this Sendmail service will receive mail.

The default name provided is the local computer's NT domain name, prefixed with the local computer name. You may wish to remove the computer name prefix if this is your company-wide smart host. For example, metainfo.com.

Specify a username for the POP3 service to run as. This user must have administrative privileges.

Enter the selected user's password and then confirm the password in the windows provided. The Next button is grayed-out until the password is confirmed.

When you have entered all the required information, the Setup program loads the Sendmail and POP3 installation files on your system.

When the files are copied, the Sendmail control panel displays, giving you the opportunity to set up or change the Sendmail control configuration. You will also be presented with the POP3 control panel to set up or change the POP3 configuration.

Sendmail Control Panel

From the Sendmail Control Panel, you can change the locations of the SPOOL and QUEUE directories, register Sendmail by entering a serial number, change the location of the configuration file and set up the Sendmail startup parameters.

Mail Spool Directory

This is the Sendmail directory that receives incoming mail. As mail is received, Sendmail writes it to the spool directory and then POP3 users read their messages from this directory. By default, the mail spool directory is created under the SENDMAIL directory.

Mail Queue Directory

The Mail Queue Directory stores outgoing mail that is temporarily undeliverable or that has been queued for later delivery. Undeliverable mail will be queued for retransmission. The default retry interval is 15 minutes. Each message is stored in a separate file. The queue directory also holds the incoming messages until they are written to the spool directory. By default, the mail queue directory is created under the SENDMAIL directory.

Configuration File

This is where the SENDMAIL.CF file resides.

Note: Do not edit this file with EDIT as tabs are critical and must be preserved.

POP3 Control Panel

From the POP3 Control Panel, you can modify the POP3 startup parameters, and view the current status.

Configuration changes must be made to the sendmail.cf file. Find the following section:

##################
# local info #
##################
Cwlocalhost
CP.
# 'Smart' relay host (may be null)
DS
# who I send unqualified names to (null means deliver locally)
DR
# who gets all local email traffic ($R has precedence for unqualified names)
DH
# who I masquerade as (null for no masquerading)
DM
# class L: names that should be delivered locally, even if we have a relay
# class E: names that should be exposed as from this host, even if we masquerade
#CLroot
CEAdministrator
# operators that cannot be in local usernames (i.e., network indicators)
CO @ %
# a class with just dot (for identifying canonical names)
C..
# dequoting map
Kdequote dequote

After the Cw line add the following line:

Cwdomain.com host.domain.com host

Change the DM line to:

DMdomain.com
