我想在Ubuntu Server 14.04 LTS（仅）上使用Postfix 2.11将发送到本地用户帐户的邮件转发到使用其他SMTP服务器的相应邮箱。
组态：
$ 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] 如果我发送邮件给root用户
$ echo "body"| mail -s "test" root
我在/var/log/mail.log中看到以下日志条目

所以为什么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”，则邮件通过作为中继主机提供的SMTP服务器正确发送，但是/ etc / aliases中的所有信息都将被忽略：邮件发送到[email protected]而不是某个帐户@ mydomain.tld 。
你有什么想法可能是什么问题？
我很确定你应该从mydestination中删除“mydomain.tld”。 在mydestination中的条目之间也必须有一个逗号（你写了localhost mydomain.tld）。
你在修改/ etc / aliases之后运行了“newaliases”命令吗？
