MailScanner 內容誤判

myspam上線之後,發生了一個很特殊的狀況,我們某個客人寄來的信,都會判斷有問題,信件的內容被MailScanner給擋了下來,原本以為是附件格式的關係(純文字 or RTF-HTML),要不然就是UTF8被檔成了Big5、歐洲編碼的關係,結果不是,是因為內容誤判。打開MailScanner加上去的付件之後,才發現,原來是內容有問題,請看藍色字部份。

maillog中出現calmav無法更新的訊息

在整合完postfix+MailScanner+Clam AV+F-prot+openwebmal+procmail+My Spam之後,在觀察maillog之後,會看到下面這些訊息。
重點在於一行 ClamAV updater /usr/local/bin/freshclam cannot be run
怎麼回事,用MailScanner帶起Clam AV之後卻無法順利的更新病毒資料庫
其實這個問題之前就有發生了,只是我把freshclam的指令寫在cron table中

My Spam “procmail: Skipped “|/usr/bin/php -Cq /var/www/html/myspam/web/index.php save_spam” 問題處理

終於做到Myspam和MailScanner的整合段,MailScanner把郵件丟給Spamassaissn中去判斷垃圾信之後,丟給prcmail,procmail再依據規則丟給Myspam來處理。

可是我在看procmail.log的時候,出現了一行訊息
procmail: Skipped “|/usr/bin/php -Cq /var/www/html/myspam/web/index.php save_spam”
意思是說,跳過傳給Myspam的處理程式,要怎麼解呢?

網友Tommy說是指令打錯了,我的指令完全完抄官方文件的,怎麼可能會打錯,所以Tommy的說法是有問題的。Tommy自己寫的MySpam安裝的內容和安裝手策上一樣。

查了一下酷學園的資料,原作者twu2學長有說,可能是selinux造成的,去查了一下httpd的error log
[Tue Mar 02 19:42:05 2010] [notice] caught SIGTERM, shutting down

果不其然,真的是selinux造成的,一般來說,我灌server,我都會把selinux關閉,不知道這次為什麼用DVD安裝的時候,沒有選項給我選。

好唄,關掉selinux吧!
vi /etc/selinux/config

SELINUX=enforcing===>SELINUX=disable

存檔 離開

修改 /etc/procmailrc

改一下規則,promailrc規則寫法不太一樣
官方的寫法是
:0
* ^X-Spam-Status: Yes{
:0: * ! ^X-MySPAM: YES
|/usr/bin/php -Cq /var/www/html/myspam/web/index.php save_spam
}

訊息是說
procmail: Skipped “|/usr/bin/php -Cq /var/www/html/myspam/web/index.php save_spam”
procmail: Closing brace unexpected
我在猜是因為{放在YES的後面照成的
去看了procmail的官法網頁
所以做了上面的規則改寫
LOGFILE=/var/log/procmail.log
MAILDIR=/var/mail

:0
* ^X-Spam-Status: Yes
{
:0
* ! ^X-MySPAM: YES
|/usr/bin/php -Cq /website/jlspam/web/index.php save_spam
}

:0 B
* ^X-Spam-Status: Yes
{
:0b
* ^X-MySPAM: YES
$DEFAULT
}

:0b
* ^X-Spam-Flag: YES
$DEFAULT

:0
* ^X-MySPAM: YES
$DEFAULT

重新開機….因為selinux改動了很多東西的設定
重開機會正常一點

==>再來玩MySpam吧!

PS.要一起看4個LOG真累(/var/log/maillog, /var/log/procmail/procmail.log,/var/log/httpd/access_log,/var/log/httpd/error_log)
