    is the file /etc/postfix/main.cf still intact?

    also how are you editing it and with what user? maybe you are changing the permissions of the file so postfix can't read it. do
    Code:
    ls -l /etc/postfix
    to see who the user group owner is of the files in postfix and see if main.cf is different.

    report back results.

    main.cf


    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.
    #
    
    # 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.
    #
    
    # 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 = localhost
    
    # 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, $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.

    # 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.

    # 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)

    # 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 = 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.

    ok, thats wierd. try this (your init scripts may be in a different location)
    Code:
    /etc/init.d/postfix start
    and then
    Code:
    tail /var/log/mail.err
    let me know the results. if you had problems with either of the above let me know what distro you are using (even though you might already have)
