Postfix Clamav MailScanner 阻擋廣告信與病毒信

作業環境 FreeBSD 6.0

Step.1 安裝 postfix

 # cd /usr/ports/mail/postfix21
 # make install clean

Step.2 安裝 Clamav

 #cd /usr/ports/security/clamav     
 #make install clean

Step.3 安裝 MailScaaner

 #cd /usr/ports/mail/mailscanner      
 #make install clean
 #make initial-config  //產生相關設定檔

Step.4 修改 postfix 設定

 #vi /usr/local/etc/postfix/main.cf 
 header_checks = regexp:/usr/local/etc/postfix/header_checks

 修改 header_checks 檔案
 # echo "/^Received:/ HOLD" >> /usr/local/etc/postfix/header_checks

Step.5 修改 MailScanner 設定

 # vi /usr/local/etc/MailScanner/MailScanner.conf
  Run As User = postfix
  Run As Group = postfix
  Incoming Queue Dir = /var/spool/postfix/hold
  Outgoing Queue Dir = /var/spool/postfix/incoming
  MTA = postfix
  Virus Scanners = clamav
  Use SpamAssassin = yes
 # vi /usr/local/etc/MailScanner/virus.scanners.conf //請先修改權限
  clamav          /usr/local/libexec/MailScanner/clamav-wrapper   /usr/local

 詳細設定請參考 http://www.mailscanner.info/man/MailScanner.conf.5.html

Step.6 建立相關目錄

 # mkdir /var/spool/MailScanner
 # mkdir /var/spool/MailScanner/incoming
 # mkdir /var/spool/MailScanner/quarantine
 # chown postfix:postfix /var/spool/MailScanner/incoming
 # chown postfix:postfix /var/spool/MailScanner/quarantine
 # chmod -R 777 /var/spool/postfix
 # touch /usr/local/etc/MailScanner/rules/bounce.rules
 # touch /usr/local/etc/MailScanner/rules/max.message.size.rules
 # cd /usr/local/etc/MailScanner/mcp
 # cp 10_example.cf.sample 10_example.cf
 # cp mcp.spam.assassin.prefs.conf.sample mcp.spam.assassin.prefs.conf  

Step.7 修改 /etc/rc.conf

    sendmail_enable="NONE"
    postfix_enable="YES" 
    clamav_clamd_enable="YES"
    clamav_freshclam_enable="YES"
    mailscanner_enable="YES"

Step.8 啟動服務

 #/usr/local/etc/rc.d/postfix.sh start
 #/usr/local/etc/rc.d/mailscanner.sh start
 #/usr/local/etc/rc.d/clamav-freshclam.sh start
 #/usr/local/etc/rc.d/clamav_clamd.sh start
