后缀：发送邮件或解析别名都有效

  • 772

我想在 Ubuntu Server 14.04 LTS（仅限）上使用 Postfix 2.11 将发送到本地用户帐户的邮件转发到使用另一个 SMTP 服务器的相应邮箱。

配置：

$ postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
inet_interfaces = loopback-only
inet_protocols = all
mailbox_size_limit = 0
mydestination = localhost mydomain.tld, myhostname, localhost.localdomain, localhost
myhostname = myhostname
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
relayhost = my-target-smtp-server
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtpd_use_tls = yes

$ cat /etc/aliases
root: [email protected]

如果我向 root 用户发送邮件

$ echo "body"| mail -s "test" root

我在/var/log/mail.log中看到以下日志条目

Nov  6 12:40:19 myhostname postfix/qmgr[1855]: D21A344EC4: removed

那么出于什么原因，postfix 不会使用中继服务器来转发邮件。如果我从mydestination中删除了 'mydomain.tld' ，邮件将通过作为relayhost提供的 SMTP 服务器正确发送，但/etc/aliases中的所有信息都会被忽略：邮件被发送到[email protected]而不是some-account @mydomain.tld。

你知道问题可能是什么吗？

    我很确定您应该从 mydestination 中删除“mydomain.tld”。mydestination 中的条目之间也必须有一个逗号（您已经编写了 localhost mydomain.tld）。

    修改 /etc/aliases 后是否运行过“newaliases”命令？
