我有 do.ma.in 及其以下 DNS 记录：
do.ma.in A a.b.c.d
mail.do.ma.in A a.b.c.d
do.ma.in MX mail.do.ma.in
我希望收到一封来自mail.google.com我的 postfix 的邮件，只发往一个地址[email protected]，或者至少发往[email protected]
因此，我安装了纯净的postfix机器a.b.c.d并编辑了下一个选项 /etc/postfix/main.cf：
myhostname = mail.do.ma.in
mydomain =do.ma.in
smtpd_recipient_restrictions = permit
其他设置都是默认的。然后我完全重启了 postfix 守护进程service postfix restart。但是当我发送邮件到 时，[email protected]我在邮件日志中看不到任何内容，只有在守护进程重启时生成的“已启动”消息：
Feb 11 19:20:29 CentOSPC postfix/master[16510]: daemon started -- version 2.6.6, configuration /etc/postfix
postqueue -p也是空的
但是，如果我捕获到 25 端口的流量，tcpdump -vv -x -X -s 1500 -i eth1 'port 25'当我从 gmail 发送邮件时，我会看到一些内容（我的主机是192.168.0.48，并且 25 端口是从主机 NAT 的192.168.0.49，它与 有接口a.b.c.d）：

那么我错过了什么，需要将哪些选项添加到配置中？
这是postconf -n
[root@CentOSPC]# 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 = localhost
inet_protocols = all
mail_owner = postfix
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain, localhost, do.ma.in
mydomain = do.ma.in
myhostname = mail.do.ma.in
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES
sample_directory = /usr/share/doc/postfix-2.6.6/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
smtpd_recipient_restrictions = permit
unknown_local_recipient_reject_code = 550
答案1
您需要将本地交付的域（在您的情况下为 do.ma.in）分配给mydestination变量main.cf
mydestination = $myhostname, localhost.$mydomain, localhost, do.ma.in
