[root@linux]# vi /etc/postfix/main.cf ← 入力 # Global Postfix configuration file. This file lists only a subset # of all 300+ parameters. See the postconf(5) manual page for a # complete list. # # The general format of each line is: parameter = value. Lines # that begin with whitespace continue the previous line. A value can # contain references to other $names or ${name}s. # # NOTE - CHANGE NO MORE THAN 2-3 PARAMETERS AT A TIME, AND TEST IF # POSTFIX STILL WORKS AFTER EVERY CHANGE. # SOFT BOUNCE # # The soft_bounce parameter provides a limited safety net for # testing. When soft_bounce is enabled, mail will remain queued that # would otherwise bounce. This parameter disables locally-generated # bounces, and prevents the SMTP server from rejecting mail permanently # (by changing 5xx replies into 4xx replies). However, soft_bounce # is no cure for address rewriting mistakes or mail routing mistakes. # #soft_bounce = no # LOCAL PATHNAME INFORMATION # # The queue_directory specifies the location of the Postfix queue. # This is also the root directory of Postfix daemons that run chrooted. # See the files in examples/chroot-setup for setting up Postfix chroot # environments on different UNIX systems. # queue_directory = /var/spool/postfix # The command_directory parameter specifies the location of all # postXXX commands. # command_directory = /usr/sbin # The daemon_directory parameter specifies the location of all Postfix # daemon programs (i.e. programs listed in the master.cf file).

In # particular, don't specify nobody or daemon. PLEASE USE A DEDICATED # USER. # mail_owner = postfix # The default_privs parameter specifies the default rights used by # the local delivery agent for delivery to external file or command. # These rights are used in the absence of a recipient user context. # DO NOT SPECIFY A PRIVILEGED USER OR THE POSTFIX OWNER. # #default_privs = nobody # INTERNET HOST AND DOMAIN NAMES # # The myhostname parameter specifies the internet hostname of this # mail system.

By default, # the software claims all active interfaces on the machine. The # parameter also controls delivery of mail to user@[ip.address]. # # See also the proxy_interfaces parameter, for network addresses that # are forwarded to us via a proxy or network address translator. # # Note: you need to stop/start Postfix when this parameter changes. # #inet_interfaces = all #inet_interfaces = $myhostname #inet_interfaces = $myhostname, localhost #inet_interfaces = localhost inet_interfaces = all # The proxy_interfaces parameter specifies the network interface # addresses that this mail system receives mail on by way of a # proxy or network address translation unit.
