我已经在我的机器上configuration了PostFix作为空客户端，就像这里所说的那样。
但是一些邮件被反弹了。 我检查了日志，发现在那里，“from”值等于机器上的脚本用户名，而不是电子邮件中的电子邮件地址：

(in reply to RCPT TO command))
我如何正确设置后缀？
电子邮件是通过使用“sendmail”二进制文件（后缀replace它）的PHP脚本发送的。
PostFixconfiguration：
[root@server2 log]# 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 debug_peer_level = 2 debug_peer_list = 127.0.0.1 html_directory = no inet_interfaces = loopback-only local_transport = error:local delivery is disabled mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop unknown_local_recipient_reject_code = 550
要设置来自：电子邮件地址，您需要使用sendmail二进制文件的-f选项。
第二个反弹可能是由relay_host指向服务器（mx.yandex.ru）不会中继邮件为您的服务器。
