如何刪除 Received: (from apache@localhost) and sendmail version from headers

如何從消息中刪除 Received 標頭？

我想隱藏 apache 使用者名和 sendmail 版本。

消息（從 PHP 腳本發送）：

請注意Received: internal info suppressed（這是我隱藏收到的標頭的嘗試之一）

我嘗試了幾個小時的一切……

變化php.ini：

sendmail_path = /usr/sbin/sendmail -t -i -fno-reply@mailer.mydomain.co.uk

（它之所以有效，是因為我有 X-Authentication-Error 警告，我通過將 apache 添加到受信任的使用者來超越它）

變化sendmail.mc：

MASQUERADE_AS(`mailer.mydomain.co.uk')dnl
FEATURE(masquerade_envelope)dnl
FEATURE(masquerade_entire_domain)dnl
FEATURE(allmasquerade)dnl 
MASQUERADE_DOMAIN(localhost)dnl
MASQUERADE_DOMAIN(localhost.localdomain)dnl
MASQUERADE_DOMAIN(erp.mydomain.co.uk)dnl
define(`confDOMAIN_NAME', `mailer.mydomain.co.uk')dnl
define(`confRECEIVED_HEADER', `internal info suppressed')dnl

生成sendmail.cf：

        (subdomain name) $m = mydomain.co.uk
             (node name) $k = erp.mydomain.co.uk
========================================================

我沒有想法，我想做的就是擺脫這個標題：

Received: (from apache@localhost)
   by mailer.mydomain.co.uk (8.14.4/8.14.4/Submit) id t8UDFgZp002574;
   Wed, 30 Sep 2015 14:15:42 +0100

我怎樣才能做到這一點？

我正在使用 Centos 6.7

我真的不想使用 postfix，因為一些伺服器軟體已經在使用 sendmail，我不想安裝兩個 MTA

好的，我發現了問題。我不得不把

define(`confRECEIVED_HEADER', `internal info suppressed')dnl

進submit.mc也。

我一直在尋找解決方案幾個小時，我不敢相信我在我在這裡發布問題後就想通了。

將此添加到 sendmail.mc 對我來說是一個更好的解決方案：

define(`confRECEIVED_HEADER',`$?{auth_type}from auth (localhost [127.0.0.1]) $|_REC_HDR_$.
   _REC_BY_
   _REC_TLS_
   _REC_END_')

這有條件地查看 auth_type，如果有身份驗證，則顯示 localhost，如果沒有，例如，如果消息從外部到達，您將獲得正常接收的標頭。這絕對是你想要的。

參考和歸功於：Sendmail 中經過身份驗證的發件人的 IP 抑制
