我最近在 Ubuntu Natty 上安装了 postfix。我在配置方面遇到了问题。
首先这是我的 postfix 配置文件：
# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
myorigin = /etc/mailname
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
delay_warning_time = 4h
readme_directory = no
# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.
mydomain = $myorigin
myhostname = mail.nairanode.com
alias_maps = hash:/etc/postfix/aliases
alias_database = hash:/etc/postfix/aliases
# this specifies where the virtual mailbox folders will be located
virtual_mailbox_base = /var/spool/mail/virtual
# this specifies where the virtual mailbox folders will be located
virtual_mailbox_base = /var/spool/mail/virtual
# this is for the mailbox location for each user
virtual_mailbox_maps = mysql:/etc/postfix/mysql_mailbox.cf
# and this is for aliases
virtual_alias_maps = mysql:/etc/postfix/mysql_alias.cf
# and this is for domain lookups
virtual_mailbox_domains = mysql:/etc/postfix/mysql_domains.cf
# this is how to connect to the domains (all virtual, but the option is there)
# not used yet
# transport_maps = mysql:/etc/postfix/mysql_transport.cf
virtual_uid_maps = static:5000
virtual_gid_maps = static:5000
mydestination = $myorigin, $myhostname, localhost.localdomain, , localhost
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
#mynetworks_style = host
# ADDITIONAL
unknown_local_recipient_reject_code = 550
maximal_queue_lifetime = 7d
minimal_backoff_time = 1000s
maximal_backoff_time = 8000s
smtp_helo_timeout = 60s
smtpd_recipient_limit = 16
smtpd_soft_error_limit = 3
smtpd_hard_error_limit = 12
# Requirements for the HELO statement
smtpd_helo_restrictions = permit_mynetworks, warn_if_reject reject_non_fqdn_hostname, reject_invalid_hostname, permit
# Requirements for the sender details
smtpd_sender_restrictions = permit_mynetworks, warn_if_reject reject_non_fqdn_sender, reject_unknown_sender_domain, reject_unauth_$
# Requirements for the connecting server
smtpd_client_restrictions = reject_rbl_client sbl.spamhaus.org, reject_rbl_client blackholes.easynet.nl, reject_rbl_client dnsbl.n$
# Requirement for the recipient address
smtpd_recipient_restrictions = reject_unauth_pipelining, permit_mynetworks, reject_non_fqdn_recipient, reject_unknown_recipient_do$
# require proper helo at connections
smtpd_helo_required = yes
# waste spammers time before rejecting them
smtpd_delay_reject = yes
disable_vrfy_command = yes
这也是我的 /etc/postfix/aliases：
# See man 5 aliases for format
postmaster: root
这也是我的 /etc/mailname：
nairanode.com
我还将主机名更新为 nairanode.com
但是，当我运行时，postalias /etc/postfix/aliases我得到以下信息：
postalias: warning: valid_hostname: invalid character 47(decimal): /etc/mailname
postalias: fatal: file /etc/postfix/main.cf: parameter mydomain: bad parameter value: /etc/mailname
我是不是做错了什么？！我注意到，当我在 postfix 配置中替换myorigin = /etc/mailname为时myorigin = nairanode.com，调用 postalias 后就看不到任何错误了。这是 bug 还是其他什么？！
答案1
您无权指定
mydomain = $myorigin
您可以完全删除该设置，也可以指定一个有效条目，例如 mail.nairanode.com。但您不能使用 $myorigin 之类的变量！
如果你希望它可以通过外部文件“动态”配置，那么你必须删除mydomain 和 myhostname完全。在这种情况下，将从主机名中提取域，并从中提取主机名/etc/hosts（更好：通过 gethostname() 系统调用）
看看你的前三行，main.cf为什么你现在遇到了 Debian-Postfix“错误”。但 Debian/Ubuntu 故意破解 Postfix 以允许这种愚蠢的事情。但他们没有考虑通过 Postfix $variables 使用此破解的后果。向 Debian 投诉，而不是 Postfix！
