[FreeBSD] 讓 Mail Server 支援 POP3 / POP3s / IMAP / IMAPs 功能 - 安裝 dovecot

測試環境：

• FreeBSD 7 -  FreeBSD 7.0-RELEASE-p12

步驟：

1. 編譯與安裝
   
   
   
   • # cd /usr/ports/mail/dovecot ; make install clean ; // 預設就很 ok 了
   
   
   
   


2. 建立 SSL 相關資料
   
   
   
   • # openssl req -new -x509 -nodes -out /tmp/public.pem -keyout /tmp/private.pem -days 3650
     
     
     
     • Country Name (2 letter code) [AU]:TW
       State or Province Name (full name) [Some-State]:Taiwan
       Locality Name (eg, city) []:ChiaYi County
       Organization Name (eg, company) [Internet Widgits Pty Ltd]:CYY
       Organizational Unit Name (eg, section) []:CYY
       Common Name (eg, YOUR name) []:
       Email Address []:admin@localhost
     
     
     
     
   
   
   • # cd /etc/ssl/ ; mkdir certs private ; chmod 700 certs private
   
   
   • # cp /tmp/public.pem /etc/ssl/certs/dovecot.pem ; cp /tmp/private.pem /etc/ssl/private/dovecot.pem
   
   
   • # rm -rf /tmp/public.pem /tmp/private.pem
   
   
   
   


3. 啟動
   
   
   
   • # vim /etc/rc.conf
     
     
     
     • dovecot_enable="YES"
     
     
     
     
   
   
   • # /usr/local/etc/rc.d/dovecot start
   
   
   
   

如此一來，即可使用，可使用以下方式測試

• POP3
  
  
  
  • # telnet localhost 110
  
  
  
  


• POP3s
  
  
  
  • # telnet localhost 995
  
  
  
  


• IMAP
  
  
  
  • # telnet localhost 143
  
  
  
  


• IMAPs
  
  
  
  • # telnet localhost 993
  
  
  
  

指令

• POP3
  
  
  
  • USER id
  
  
  • PASS password
  
  
  • QUIT
