postfix+dovecot只能发邮件,不能收取
采用的是centos5.8 目前可以正常发送邮件是外部邮件服务器,但是不能正常收取邮件。不管是内部还是外部邮件都没有收取。
也查看了osc上面一个提问中提供的配置教程,可能是小弟太菜,仍然没有发现问题所在。现在是配置文件。

# 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. # 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 # 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. # 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 = mail.ayzd.cn #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.ayzd.cn # 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 # 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 # 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 # The mailbox_command parameter specifies the optional external # command to use instead of mailbox delivery. The command is run as # the recipient with proper HOME, SHELL and LOGNAME environment settings. # Exception: delivery for root is done as $default_user. # # Other environment variables of interest: USER (recipient username), # EXTENSION (address extension), DOMAIN (domain part of address), # and LOCAL (the address localpart). # # Unlike other Postfix configuration parameters, the mailbox_command # parameter is not subjected to $parameter substitutions. This is to # make it easier to specify shell syntax (see example below). # # Avoid shell meta characters because they will force Postfix to run # an expensive shell process. Procmail alone is expensive enough. # # IF YOU USE THIS TO DELIVER MAIL SYSTEM-WIDE, YOU MUST SET UP AN # ALIAS THAT FORWARDS MAIL FOR ROOT TO A REAL USER. # #mailbox_command = /some/where/procmail #mailbox_command = /some/where/procmail -a "$EXTENSION" # The mailbox_transport specifies the optional transport in master.cf # to use after processing aliases and .forward files.

This is the same as the old default_mail_env # setting. The default is empty, which means that Dovecot tries to find the # mailboxes automatically. This won't work if the user doesn't have any mail # yet, so you should explicitly tell Dovecot the full location. # # If you're using mbox, giving a path to the INBOX file (eg. /var/mail/%u) # isn't enough. You'll also need to tell Dovecot where the other mailboxes are # kept. This is called the "root mail directory", and it must be the first # path given in the mail_location setting. # # There are a few special variables you can use, eg.: # # %u - username # %n - user part in user@domain, same as %u if there's no domain # %d - domain part in user@domain, empty if there's no domain # %h - home directory # # See <doc/wiki/Variables.txt> for full list.

Private namespaces # are for user's personal mails. Shared namespaces are for accessing other # users' mailboxes that have been shared. Public namespaces are for shared # mailboxes that are managed by sysadmin. If you create any shared or public # namespaces you'll typically want to enable ACL plugin also, otherwise all # users can access all the shared mailboxes, assuming they have permissions # on filesystem level to do so. # # REMEMBER: If you add any namespaces, the default namespace must be added # explicitly, ie. mail_location does nothing unless you have a namespace # without a location setting. Default namespace is simply done by having a # namespace with empty prefix. #namespace private { # Hierarchy separator to use. You should use the same separator for all # namespaces or some clients get confused.

This needs to be different for # all namespaces. For example "Public/". #prefix = # Physical location of the mailbox. This is in same format as # mail_location, which is also the default for it. #location = # There can be only one INBOX, and this setting defines which namespace # has it. #inbox = no # If namespace is hidden, it's not advertised to clients via NAMESPACE # extension. You'll most likely also want to set list=no. This is mostly # useful when converting from another server with different namespaces which # you want to deprecate but still keep working.

You can also optionally give a global ACL directory path where # ACLs are applied to all users' mailboxes. The global ACL directory contains # one file for each mailbox, eg.

Mails are expunged from mailboxes after being there the # configurable time. The first expiration date for each mailbox is stored in # a dictionary so it can be quickly determined which mailboxes contain # expired mails.

Currently works only with maildirs. When a user # expunges mails, the mails are moved to a mailbox in another namespace # (1st). When a mailbox is deleted, the mailbox is moved to another namespace # (2nd) as well. Also if the deleted mailbox had any expunged messages, # they're moved to a 3rd namespace. The mails won't be counted in quota, # and they're not deleted automatically (use a cronjob or something). #lazy_expunge = .EXPUNGED/ .DELETED/ .DELETED/.EXPUNGED/ # Events to log.

这是来挖坟了么
是怎么通过25端口发往外域的
谢谢 我试试
我这里 postfix + dovecot 成功收发, 文档和配置文件在此
