CentOS7 安裝 iRedMail Mail Server

環境準備

  • 關閉 selinux 
    vi /etc/selinux/config
    :
SELINUX=disabled
  • 設定 /etc/sysconfig/network 
    HOSTNAME=iredmail.ichiayi.com
  • 設定 /etc/hosts 
    127.0.0.1   iredmail.ichiayi.com iredmail localhost localhost.localdomain
  • 設定 /etc/hostname 
    iredmail.ichiayi.com
  • 重新開機
    sync;sync;sync;reboot

下載安裝 iRedMail

su - root
yum install wget bzip2
cd /root/
wget https://bitbucket.org/zhb/iredmail/downloads/iRedMail-0.9.9.tar.bz2
tar xjf iRedMail-0.9.9.tar.bz2
cd /root/iRedMail-0.9.9/
bash iRedMail.sh
  • 安裝完成最後更新完成掃毒病毒碼 daily.cld 之後, 要重新開機所有服務才能正常啟動
    sync;sync;sync;reboot
  • 如果執行安裝時一直出現 /etc/hosts 的設定錯誤, 請先用 
    hostname -f

    是否能夠正確出現標準 FQDN 格式 Exp. iredmai.ichiayi.com

  • 如果是安裝在中國機房, 因為 iredmail.org 被 GFW 封鎖, 所以要改用以下語法
    IREDMAIL_EPEL_MIRROR='http://mirrors.aliyun.com/epel'
IREDMAIL_MIRROR='https://dl.iredmail.org' bash iRedMail.sh
  • 安裝完成後重要資訊會產生在 /root/iRedMail-0.9.8/iRedMail.tips 檔案內

相關設定與驗證測試

修改主機名稱的處理方式

SSL 憑證設定

  • 設定 SSL 憑證 : https://docs.iredmail.org/use.a.bought.ssl.certificate.html
    • 取得免費的 LetsEncrypt ssl 憑證 參考 - 申請設定 Let's Encrypt 免費 SSL 憑證(CentOS + Apache/Nginx)
      • Exp. 取得的憑證存放在 /etc/letsencrypt/live/mail.ichiayi.com/
    • 設定 Postfix (SMTP server) 執行命令
    • 設定 Dovecot (POP3/IMAP server) 參考設定內容
    • 設定 WebMail(nginx) 參考執行命令
    • 確認設定的 SSL 憑證有正式運作
      • IMAP 執行命令
      • POP3 執行命令
      • SMTP 執行命令
      • Web 執行命令
  • 如果 SSL 憑證與 Mail Server 在不同主機上, 每次憑證更新後可透過 rsync 方式來進行跨主機同步
  • Exp. SSL 憑證存在 192.168.11.234 主機上, 可在 Mail Server 執行以下的同步語法:

白名單與黑名單設定

郵件移轉 (imapsync)

  • 是透過新舊 Mail Server 的 imap 協定來將舊 Mail Server 內的信件移轉至新 Mail Server 內
  • 安裝 imapsync 
    yum install imapsync
  • 假設要移轉 jonathan 的信件, 要知道新舊主機 jonathan 的密碼, 將密碼寫入 /root/sync_info/jonathan 檔案內, 然後執行以下的語法 
    imapsync --host1 mail.ichiayi.com --user1 jonathan --passfile1 /root/sync_info/jonathan --host2 192.168.11.236 --user2 jonathan --passfile2 /root/sync_info/jonathan
  • 執行後, 會在執行目錄底下產生 LOG_imapsync 目錄, 裡面會有執行過程的紀錄檔案 Exp. 2018_09_07_11_35_30_testalbert.txt
  • 記錄檔內出現 Err 的項目表示同步時出現異常的信件匣, 需要另外處理 Exp.
    Err 1/2: Could not create folder [from Albert/&ZbBbomI2--Data/INDIA/ABC.] from [from Albert/&ZbBbomI2--Data/INDIA/ABC.]: 38252 NO [CANNOT] Character not allowed in mailbox name: '.' (0.001 + 0.000 secs).

出現 postfix/amavis/smtp[6831]: connect to 127.0.0.1[127.0.0.1]:10024: Connection refused 問題

  • 2020/08 之後開始出現這問題, 快速解決方式是將 amavisd 服務啟動
    systemctl start amavisd
systemctl enable amavisd

忘記 iRedAdmin 登入的管理者密碼處理方式

  • 可以直接透過資料庫加上一位現有的信箱用戶當管理者 Exp. [email protected]
  • 登入 iRedMail 的資料庫

    mysql -u root -p
USE vmail;
select isadmin,isglobaladmin from mailbox where username = '[email protected]';
UPDATE mailbox SET isadmin=1, isglobaladmin=1 WHERE  username = '[email protected]';
INSERT INTO domain_admins (username, domain) VALUES ('[email protected]', 'ALL');

  • 看詳細過程

    mysql -u root -p
MariaDB [(none)]> USE vmail;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
MariaDB [vmail]> select isadmin,isglobaladmin from mailbox where username = '[email protected]';
+---------+---------------+
| isadmin | isglobaladmin |
+---------+---------------+
|       0 |             0 |
+---------+---------------+
1 row in set (0.00 sec)

MariaDB [vmail]> UPDATE mailbox SET isadmin=1, isglobaladmin=1 WHERE  username = '[email protected]';
Query OK, 1 row affected (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 0

MariaDB [vmail]>  INSERT INTO domain_admins (username, domain) VALUES ('[email protected]', 'ALL');
Query OK, 1 row affected (0.00 sec)
MariaDB [vmail]> exit
Bye
