LinuxQuestions.org - [SOLVED] postfix is simply refusing to run

When i try to restart my postfix mail server on my Linux CentOS Dedicated Server i get the following:

Code:

# /etc/init.d/postfix restart



Shutting down postfix:                                    [FAILED]

Starting postfix:                                          [  OK  ]

In the logs i can see:

Code:

# Global Postfix configuration file. This file lists only a subset

# of all parameters. For the syntax, and for a complete parameter

# list, see the postconf(5) manual page (command: "man 5 postconf").

#

# For common configuration examples, see BASIC_CONFIGURATION_README

# and STANDARD_CONFIGURATION_README. To find these documents, use

# the command "postconf html_directory readme_directory", or go to

# http://www.postfix.org/.

#

# For best results, 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). This

# directory must be owned by root.

#

daemon_directory = /usr/libexec/postfix



# QUEUE AND PROCESS OWNERSHIP

#

# The mail_owner parameter specifies the owner of the Postfix queue

# and of most Postfix daemon processes.  Specify the name of a user

# account THAT DOES NOT SHARE ITS USER OR GROUP ID WITH OTHER ACCOUNTS

# AND THAT OWNS NO OTHER FILES OR PROCESSES ON THE SYSTEM.  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. The default is to use the fully-qualified domain name

# from gethostname(). $myhostname is used as a default value for many

# other configuration parameters.

#

#myhostname = host.domain.tld

#myhostname = virtual.domain.tld



# The mydomain parameter specifies the local internet domain name.

# The default is to use $myhostname minus the first component.

# $mydomain is used as a default value for many other configuration

# parameters.

#

#mydomain = domain.tld



# SENDING MAIL

# 

# The myorigin parameter specifies the domain that locally-posted

# mail appears to come from. The default is to append $myhostname,

# which is fine for small sites.  If you run a domain with multiple

# machines, you should (1) change this to $mydomain and (2) set up

# a domain-wide alias database that aliases each user to

# user@that.users.mailhost.

#

# For the sake of consistency between sender and recipient addresses,

# myorigin also specifies the default domain name that is appended

# to recipient addresses that have no @domain part.

#

#myorigin = $myhostname

#myorigin = $mydomain



# RECEIVING MAIL



# The inet_interfaces parameter specifies the network interface

# addresses that this mail system receives mail on.  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 = 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. This setting extends

# the address list specified with the inet_interfaces parameter.

#

# You must specify your proxy/NAT addresses when your system is a

# backup MX host for other domains, otherwise mail delivery loops

# will happen when the primary MX host is down.

#

#proxy_interfaces =

#proxy_interfaces = 1.2.3.4



# The mydestination parameter specifies the list of domains that this

# machine considers itself the final destination for.

#

# These domains are routed to the delivery agent specified with the

# local_transport parameter setting. By default, that is the UNIX

# compatible delivery agent that lookups all recipients in /etc/passwd

# and /etc/aliases or their equivalent.

#

# The default is $myhostname + localhost.$mydomain.  On a mail domain

# gateway, you should also include $mydomain.

#

# Do not specify the names of virtual domains - those domains are

# specified elsewhere (see VIRTUAL_README).

#

# Do not specify the names of domains that this machine is backup MX

# host for. Specify those names via the relay_domains settings for

# the SMTP server, or use permit_mx_backup if you are lazy (see

# STANDARD_CONFIGURATION_README).

#

# The local machine is always the final destination for mail addressed

# to user@[the.net.work.address] of an interface that the mail system

# receives mail on (see the inet_interfaces parameter).

#

# Specify a list of host or domain names, /file/name or type:table

# patterns, separated by commas and/or whitespace. A /file/name

# pattern is replaced by its contents; a type:table is matched when

# a name matches a lookup key (the right-hand side is ignored).

# Continue long lines by starting the next line with whitespace.

#

# See also below, section "REJECTING MAIL FOR UNKNOWN LOCAL USERS".

#

mydestination = $myhostname, localhost.$mydomain, localhost

#mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain

#mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain,

#        mail.$mydomain, www.$mydomain, ftp.$mydomain



# REJECTING MAIL FOR UNKNOWN LOCAL USERS

#

# The local_recipient_maps parameter specifies optional lookup tables

# with all names or addresses of users that are local with respect

# to $mydestination, $inet_interfaces or $proxy_interfaces.

#

# If this parameter is defined, then the SMTP server will reject

# mail for unknown local users. This parameter is defined by default.

#

# To turn off local recipient checking in the SMTP server, specify

# local_recipient_maps = (i.e. empty).

#

# The default setting assumes that you use the default Postfix local

# delivery agent for local delivery. You need to update the

# local_recipient_maps setting if:

#

# - You define $mydestination domain recipients in files other than

#  /etc/passwd, /etc/aliases, or the $virtual_alias_maps files.

#  For example, you define $mydestination domain recipients in    

#  the $virtual_mailbox_maps files.

#

# - You redefine the local delivery agent in master.cf.

#

# - You redefine the "local_transport" setting in main.cf.

#

# - You use the "luser_relay", "mailbox_transport", or "fallback_transport"

#  feature of the Postfix local delivery agent (see local(8)).

#

# Details are described in the LOCAL_RECIPIENT_README file.

#

# Beware: if the Postfix SMTP server runs chrooted, you probably have

# to access the passwd file via the proxymap service, in order to

# overcome chroot restrictions. The alternative, having a copy of

# the system passwd file in the chroot jail is just not practical.

#

# The right-hand side of the lookup tables is conveniently ignored.

# In the left-hand side, specify a bare username, an @domain.tld

# wild-card, or specify a user@domain.tld address.

# 

#local_recipient_maps = unix:passwd.byname $alias_maps

#local_recipient_maps = proxy:unix:passwd.byname $alias_maps

#local_recipient_maps =



# The unknown_local_recipient_reject_code specifies the SMTP server

# response code when a recipient domain matches $mydestination or

# ${proxy,inet}_interfaces, while $local_recipient_maps is non-empty

# and the recipient address or address local-part is not found.

#

# The default setting is 550 (reject mail) but it is safer to start

# with 450 (try again later) until you are certain that your

# local_recipient_maps settings are OK.

#

unknown_local_recipient_reject_code = 550



# TRUST AND RELAY CONTROL



# The mynetworks parameter specifies the list of "trusted" SMTP

# clients that have more privileges than "strangers".

#

# In particular, "trusted" SMTP clients are allowed to relay mail

# through Postfix.  See the smtpd_recipient_restrictions parameter

# in postconf(5).

#

# You can specify the list of "trusted" network addresses by hand

# or you can let Postfix do it for you (which is the default).

#

# By default (mynetworks_style = subnet), Postfix "trusts" SMTP

# clients in the same IP subnetworks as the local machine.

# On Linux, this does works correctly only with interfaces specified

# with the "ifconfig" command.

# 

# Specify "mynetworks_style = class" when Postfix should "trust" SMTP

# clients in the same IP class A/B/C networks as the local machine.

# Don't do this with a dialup site - it would cause Postfix to "trust"

# your entire provider's network.  Instead, specify an explicit

# mynetworks list by hand, as described below.

#  

# Specify "mynetworks_style = host" when Postfix should "trust"

# only the local machine.

# 

#mynetworks_style = class

#mynetworks_style = subnet

#mynetworks_style = host



# Alternatively, you can specify the mynetworks list by hand, in

# which case Postfix ignores the mynetworks_style setting.

#

# Specify an explicit list of network/netmask patterns, where the

# mask specifies the number of bits in the network part of a host

# address.

#

# You can also specify the absolute pathname of a pattern file instead

# of listing the patterns here. Specify type:table for table-based lookups

# (the value on the table right-hand side is not used).

#

#mynetworks = 168.100.189.0/28, 127.0.0.0/8

#mynetworks = $config_directory/mynetworks

#mynetworks = hash:/etc/postfix/network_table



# The relay_domains parameter restricts what destinations this system will

# relay mail to.  See the smtpd_recipient_restrictions description in

# postconf(5) for detailed information.

#

# By default, Postfix relays mail

# - from "trusted" clients (IP address matches $mynetworks) to any destination,

# - from "untrusted" clients to destinations that match $relay_domains or

#  subdomains thereof, except addresses with sender-specified routing.

# The default relay_domains value is $mydestination.

# 

# In addition to the above, the Postfix SMTP server by default accepts mail

# that Postfix is final destination for:

# - destinations that match $inet_interfaces or $proxy_interfaces,

# - destinations that match $mydestination

# - destinations that match $virtual_alias_domains,

# - destinations that match $virtual_mailbox_domains.

# These destinations do not need to be listed in $relay_domains.

# 

# Specify a list of hosts or domains, /file/name patterns or type:name

# lookup tables, separated by commas and/or whitespace.  Continue

# long lines by starting the next line with whitespace. A file name

# is replaced by its contents; a type:name table is matched when a

# (parent) domain appears as lookup key.

#

# NOTE: Postfix will not automatically forward mail for domains that

# list this system as their primary or backup MX host. See the

# permit_mx_backup restriction description in postconf(5).

#

#relay_domains = $mydestination



# INTERNET OR INTRANET



# The relayhost parameter specifies the default host to send mail to

# when no entry is matched in the optional transport(5) table. When

# no relayhost is given, mail is routed directly to the destination.

#

# On an intranet, specify the organizational domain name. If your

# internal DNS uses no MX records, specify the name of the intranet

# gateway host instead.

#

# In the case of SMTP, specify a domain, host, host:port, [host]:port,

# [address] or [address]:port; the form [host] turns off MX lookups.

#

# If you're connected via UUCP, see also the default_transport parameter.

#

#relayhost = $mydomain

#relayhost = [gateway.my.domain]

#relayhost = [mailserver.isp.tld]

#relayhost = uucphost

#relayhost = [an.ip.add.ress]



# REJECTING UNKNOWN RELAY USERS

#

# The relay_recipient_maps parameter specifies optional lookup tables

# with all addresses in the domains that match $relay_domains.

#

# If this parameter is defined, then the SMTP server will reject

# mail for unknown relay users. This feature is off by default.

#

# The right-hand side of the lookup tables is conveniently ignored.

# In the left-hand side, specify an @domain.tld wild-card, or specify

# a user@domain.tld address.

# 

#relay_recipient_maps = hash:/etc/postfix/relay_recipients



# INPUT RATE CONTROL

#

# The in_flow_delay configuration parameter implements mail input

# flow control. This feature is turned on by default, although it

# still needs further development (it's disabled on SCO UNIX due

# to an SCO bug).

# 

# A Postfix process will pause for $in_flow_delay seconds before

# accepting a new message, when the message arrival rate exceeds the

# message delivery rate. With the default 100 SMTP server process

# limit, this limits the mail inflow to 100 messages a second more

# than the number of messages delivered per second.

# 

# Specify 0 to disable the feature. Valid delays are 0..10.

# 

#in_flow_delay = 1s



# ADDRESS REWRITING

#

# The ADDRESS_REWRITING_README document gives information about

# address masquerading or other forms of address rewriting including

# username->Firstname.Lastname mapping.



# ADDRESS REDIRECTION (VIRTUAL DOMAIN)

#

# The VIRTUAL_README document gives information about the many forms

# of domain hosting that Postfix supports.



# "USER HAS MOVED" BOUNCE MESSAGES

#

# See the discussion in the ADDRESS_REWRITING_README document.



# TRANSPORT MAP

#

# See the discussion in the ADDRESS_REWRITING_README document.



# ALIAS DATABASE

#

# The alias_maps parameter specifies the list of alias databases used

# by the local delivery agent. The default list is system dependent.

#

# On systems with NIS, the default is to search the local alias

# database, then the NIS alias database. See aliases(5) for syntax

# details.

# 

# If you change the alias database, run "postalias /etc/aliases" (or

# wherever your system stores the mail alias file), or simply run

# "newaliases" to build the necessary DBM or DB file.

#

# It will take a minute or so before changes become visible.  Use

# "postfix reload" to eliminate the delay.

#

#alias_maps = dbm:/etc/aliases

alias_maps = hash:/etc/aliases

#alias_maps = hash:/etc/aliases, nis:mail.aliases

#alias_maps = netinfo:/aliases



# The alias_database parameter specifies the alias database(s) that

# are built with "newaliases" or "sendmail -bi".  This is a separate

# configuration parameter, because alias_maps (see above) may specify

# tables that are not necessarily all under control by Postfix.

#

#alias_database = dbm:/etc/aliases

#alias_database = dbm:/etc/mail/aliases

alias_database = hash:/etc/aliases

#alias_database = hash:/etc/aliases, hash:/opt/majordomo/aliases





# DEBUGGING CONTROL

#

# The debug_peer_level parameter specifies the increment in verbose

# logging level when an SMTP client or server host name or address

# matches a pattern in the debug_peer_list parameter.

#

debug_peer_level = 2



# The debug_peer_list parameter specifies an optional list of domain

# or network patterns, /file/name patterns or type:name tables. When

# an SMTP client or server host name or address matches a pattern,

# increase the verbose logging level by the amount specified in the

# debug_peer_level parameter.

#

#debug_peer_list = 127.0.0.1

#debug_peer_list = some.domain



# The debugger_command specifies the external command that is executed

# when a Postfix daemon program is run with the -D option.

#

# Use "command .. & sleep 5" so that the debugger can attach before

# the process marches on. If you use an X-based debugger, be sure to

# set up your XAUTHORITY environment variable before starting Postfix.

#

debugger_command =

        PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin

        xxgdb $daemon_directory/$process_name $process_id & sleep 5
