使用简单过滤时，Postfix会replace“from”

我正在尝试configurationPostfix（在RHEL 6.5上）以修改传入邮件的内容并将邮件转发到远程服务器。 我使用一个Perl脚本pipe理Postfix来修改内容，并使用Sendmail将邮件注入到Postfix中。

当电子邮件第一次到达服务器时，我看到from字段被正确初始化，但它被重写：

 postfix/smtpd[29150]: connect from ** local domain **[xxxx] postfix/smtpd[29150]: 2CF665F6B9: client=** local domain **[xxxx] postfix/cleanup[29155]: 2CF665F6B9: message-id=<msg_172345> postfix/qmgr[29120]: 2CF665F6B9: from=<[email protected]>, size=66895, nrcpt=1 (queue active) postfix/pickup[29119]: 472C75F6BC: uid=600 from=<admin> postfix/cleanup[29155]: 472C75F6BC: message-id=<msg_172345> postfix/pipe[29159]: 2CF665F6B9: to=<[email protected]>, relay=myhook, delay=3.1, delays=3/0.01/0/0.06, dsn=2.0.0, status=sent (delivered via myhook service) postfix/qmgr[29120]: 2CF665F6B9: removed postfix/qmgr[29120]: 472C75F6BC: from=<admin@** local domain **>, size=67025, nrcpt=1 (queue active) 

正如你所看到的， from字段从[email protected]更改为admin@** local domain **

我假设admin来自main.cf中的pipe user=admin ，本地域来自/etc/hosts 。

• Dovecot / Postfix / SASL：连接到/ var / run / dovecot / auth-client失败：权限被拒绝
• 后缀限制从IP范围域的邮件
• validation错误通过terminal中的openssl连接到邮件服务器
• SMTP服务检测
• postfix别名maildir传递给〜user / Maildir /而不是〜user / Maildir / alias /

我需要的是保留电子邮件的原始发件人，但似乎我无法做到这一点。 你能把我指向正确的方向吗？

非常感谢。

编辑：

这是我的Postfixconfiguration：

 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 header_checks = regexp:/etc/postfix/header_checks html_directory = no inet_interfaces = $myhostname, localhost inet_protocols = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man myhostname = ** local domain ** 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 smtp_connection_cache_on_demand = yes smtpd_helo_required = no transport_maps = hash:/etc/postfix/transport unknown_local_recipient_reject_code = 550 

看来我的Postfix不接受-M标志。

这是master.cf ：

 # cat /etc/postfix/master.cf | grep -v "#" smtp inet n - n - - smtpd -o content_filter=myhook: pickup fifo n - n 60 1 pickup cleanup unix n - n - 0 cleanup qmgr fifo n - n 300 1 qmgr tlsmgr unix - - n 1000? 1 tlsmgr rewrite unix - - n - - trivial-rewrite bounce unix - - n - 0 bounce defer unix - - n - 0 bounce trace unix - - n - 0 bounce verify unix - - n - 1 verify flush unix n - n 1000? 0 flush proxymap unix - - n - - proxymap proxywrite unix - - n - 1 proxymap smtp unix - - n - - smtp relay unix - - n - - smtp -o smtp_fallback_relay= showq unix n - n - - showq error unix - - n - - error retry unix - - n - - error discard unix - - n - - discard local unix - nn - - local virtual unix - nn - - virtual lmtp unix - - n - - lmtp anvil unix - - n - 1 anvil scache unix - - n - 1 scache myhook unix - nn - - pipe flags=Rq user=admin argv=/var/tmp/filter.pl ${sender} ${recipient}
