[root@oolong postfix]# pwd /etc/postfix [root@oolong postfix]# vi main.cf # 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 myhostname = typea.bne.jp # 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 mydomain = typea.bne.jp # 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 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 # rem 20041205 inet_interfaces = localhost inet_interfaces = all # 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 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". # # rem 20041205 mydestination = $myhostname, localhost.$mydomain, localhost #mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain #mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, # mail.$mydomain, www.$mydomain, ftp.$mydomain mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain # 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 mynetwork_style = subnet # 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/ # dovecotのdefault_mail_envとあわせる home_mailbox = Mailbox
