Ubuntu/Debian 上的 Sendmail smrsh 別名腳本管道問題

兩週來，我一直在努力解決這個問題。我想要做的是將 sendmail 別名（虛擬域的集合）傳遞給 php 腳本。但是，我總是收到以下錯誤（無法直接郵寄給程序）：

10 月 7 日 14:35:49 fut-02 sm-mta

$$ 14057 $$: o97LZlmh014057: <5minutes@dev2.domain.com> … 無法直接向程序發送郵件 10 月 7 日 14:35:49 fut-02 sm-mta$$ 14057 $$: o97LZlmh014057: from=, size=0, class=0, nrcpts=0, proto=ESMTP, daemon=MTA-v4, relay=mail-ww0-f46.google.com$$ 74.125.82.46 $$ 我在我的 virtusers 文件中嘗試了以下別名：

@domain.com "|php -q /home/myuser/myscript.php"
@domain.com "|/usr/bin/php5 -q /home/myuser/myscript.php"
@domain.com "|php5 /home/myuser/myscript.php"
@domain.com "|myscript.php"
@domain.com "|php5 myscript.php"

我嘗試在 sendmail.mc 文件中啟用 smrsh 有兩種不同的方式：

FEATURE(`smrsh',`/usr/lib/sm.bin/smrsh')dnl
FEATURE(`smrsh')dnl

然後我嘗試將 /usr/bin/php、/usr/bin/php5（實際的二進製文件）和腳本本身連結到 /etc/mail/smrsh/。我也嘗試過完全禁用 smrsh。每個測試都會導致相同的錯誤。要驗證 smrsh 是否正常工作，我能夠成功執行：

/usr/lib/sm.bin/smrsh -c "/usr/bin/php5 -q /home/user/myscript.php"

我的 sendmail.mc 的副本在這篇文章的底部。

我錯過了一些明顯的東西嗎？Ubuntu/Debian sendmail 配置中是否有其他地方可以阻止向腳本發送郵件？

FWIW，我在 Ubuntu 10.10 RC 和 Debian 5 上嘗試了這個設置。除了 Debians 預設 sendmail.mc 的格式不正確（在 MAILER 指令之後有 FEATURES）之外，兩者的結果相同。

您必須修改規則集 0（或規則集 2）才能解決此問題：

LOCAL_RULE_0
R$* < @ virtualdomain.com. > $*     $#prog $: $1 @ virtualdomain.com

prog 傳遞代理在“bat book”（第 4 版）的第 727 頁進行了討論。

以上不適用於 smrsh。它假設 $#prog 被設置為一個程序，該程序根據其參數決定採取什麼行動。

您甚至可以定義自己的送貨代理，它會完全按照您的意願行事，而不是試圖適應您的情況。
