各位朋友好,我请教个问题,本人用Redhat as 5 + postfix +Dovecot 建了一个邮件服务器。在用smtp发邮件时的示relay access denied,用pop3收邮件的时候Internal login failure.不知道是什么原因?请各位高手给分析一下。我试向在本域或外域发送都发不出去,下面我附上我postfix配置文件。
- # 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
- # The data_directory parameter specifies the location of Postfix-writable
- # data files (caches, random numbers). This directory must be owned
- # by the mail_owner account (see below).
- #
- data_directory = /var/lib/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 = mail.xinxianghui.net
- #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 = mail.xinxianghui.net
- # 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 = $myhostname
- #inet_interfaces = $myhostname, 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
- #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 = 222.73.26.15/28, 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 = $mydomain
- # 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
- # ADDRESS EXTENSIONS (e.g., user+foo)
- #
- # The recipient_delimiter parameter specifies the separator between
- # user names and address extensions (user+foo). See canonical(5),
- # local(8), relocated(5) and virtual(5) for the effects this has on
- # aliases, canonical, virtual, relocated and .forward file lookups.
- # Basically, the software tries user+foo and .forward+foo before
- # trying user and .forward.
- #
- #recipient_delimiter = +
- # DELIVERY TO MAILBOX
- #
- # The home_mailbox parameter specifies the optional pathname of a
- # mailbox file relative to a user's home directory. The default
- # mailbox file is /var/spool/mail/user or /var/mail/user. Specify
- # "Maildir/" for qmail-style delivery (the / is required).
- #
- #home_mailbox = Mailbox
- #home_mailbox = Maildir/
-
- # The mail_spool_directory parameter specifies the directory where
- # UNIX-style mailboxes are kept. The default setting depends on the
- # system type.
- #
- #mail_spool_directory = /var/mail
- #mail_spool_directory = /var/spool/mail
