5.1.4.2.2 Users Automatically Excluded from Masquerading
The following users are always excluded from masquerading (whether or not you explicitly
specify them in the Excluded Users List field or in the Excluded Users File):
• root
• postmaster
• news
• uucp
• mailer-daemon
• rdist
• nobody
• daemon
• pop
• imap
5.1.4.2.3 Configuring Your System for Masquerading
To configure your system for masquerading, follow these steps:
1. To enable masquerading, turn on the Enable Masquerading checkbox. (To disable
masquerading while retaining the masquerading configuration, turn off this checkbox.)
2. Enter the masquerading host name in the Masquerade As field. This field is required. When
masquerading is enabled, all the host aliases for your system (see Section 5.1.3.1: Creating
and Deleting Host Aliases for a Mail Server) will automatically assume this masquerading
host name, unless you check Exclude Host Aliases From Masquerading (see step 8). The
system can have only one masquerading host name, and must be a valid, fully qualified
name.
3. You can specify additional hosts and domains that you want to assume the masquerading
host name by entering the names in the Masquerading Hosts/Domains List field. Separate
the names using a space. In Figure 5-1, the host server.xyzcorp.com and the domain
xyzcorp.com will assume the masquerading host name xyzcorp.com.
