4.1.1. Procedure – Configuring Postfix

Purpose: 

PNS uses Postfix as a native service for handling emails. A mail transferring agent (MTA) must be installed on the machine at least for delivering the locally generated messages.

Steps: 

1. Select the mail server configuration that best meets your needs. The following options are available:

   

   Figure 4.1. Postfix Configuration - General

   • No configuration: No configuration changes will be done. Use this option if a working Postfix configuration is already available on the host, or if you wish to configure Postfix manually from MC.

   • Internet Site: Sending and receiving mails is possible by using SMTP directly. This option is suitable in the most common scenarios.

   • Internet with smarthost: Mails are received either by using SMTP directly or by running a utility such as fetchmail. Outgoing messages are sent through another machine (a smarthost).

   • Satellite system: No mail is received locally. Root and postmaster mails are handled according to /etc/aliases. All messages are sent to another machine (a smarthost) for delivery.

   • Local only: Mails are only delivered locally on the machine for local users. There is no network.

2. Enter the name that should appear in the domain part of the outgoing mail (that is, after the @ character). This name will also be used by other programs. It should be the fully qualified domain name (FQDN).
