在SF / SO上挖了几个小时并search了很多之后，我仍然无法弄清楚postfix如何使用/ etc / aliases。
srv.example.com root: [email protected]在内的规则来设置/etc/aliases root: [email protected] newaliases来考虑/etc/aliases的更改 sudo service postfix restart echo "something" | mailx -s D"subject" root echo "something" | mailx -s D"subject" root发送邮件到[email protected]而不是[email protected] 我在/var/log/maillog跟踪了这个：

我唯一的后缀configuration修改是（ 空客户端configuration ）：
myhostname = srv.example.com myorigin = $mydomain relayhost = $mydomain inet_interfaces = loopback-only mydestination = 为了按预期方式应用/ etc / aliases语句，我错过了哪些步骤？
我的sudo postconf -n ：
alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 html_directory = no inet_interfaces = loopback-only inet_protocols = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man milter_default_action = accept mydestination = myhostname = srv.example.com myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix non_smtpd_milters = $smtpd_milters queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES relayhost = $mydomain sample_directory = /usr/share/doc/postfix-2.6.6/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_milters = inet:127.0.0.1:8891 unknown_local_recipient_reject_code = 550
在了解了一个“空客户端”是一个空客户端之后 ，我深入了解了一下如何理解postfix的虚拟域 。
myorigin到服务器主机名 myorigin also specifies the default domain name that is appended to recipient addresses that have no @domain part （取自/et/postfix/main.cf ） myorigin also specifies the default domain name that is appended to recipient addresses that have no @domain part 。 /etc/aliases路由我的本地邮件，因为我的邮件root / fail2ban / me …将被重写为[email protected] / [email protected] … [email protected]重写为[email protected] /etc/postfix/canonical添加@srv.example.com [email protected] /etc/postfix/main.cf添加canonical_maps = hash:/etc/postfix/canonical postmap /etc/postfix/canonical并重启postfix（ sudo service postfix restart ） 我进一步了解了原始目标用户的信息。 你可以使用正则expression式：
/etc/postfix/main.cf ，而不是canonical_maps = hash:/etc/postfix/canonical ，使用canonical_maps = regexp:/etc/postfix/canonical /etc/postfix/canonical ，而不是@srv.example.com [email protected] ，我用(.+)@(.+).example.com [email protected]接收邮件到mymail [email protected]（以后我会有srv2，srv3，srvx …） 我太早求助了，希望这个答案能帮助别人坚持同样的问题。
