Docker Mail Server 构建实践

目标：

构建基于docker-compose的邮件系统

步骤：

1. 配置域名 @ 记录指向邮件服务器ip

2. 建立目录: /data0/Server/Settings/docker-mailserver

3. 获取需要的脚本

cd /data0/Server/Settings/docker-mailserver

wget https://raw.githubusercontent.com/docker-mailserver/docker-mailserver/master/docker-compose.yml
wget https://raw.githubusercontent.com/docker-mailserver/docker-mailserver/master/mailserver.env

# if you're using :edge as the image tag
wget https://raw.githubusercontent.com/docker-mailserver/docker-mailserver/master/setup.sh

chmod a+x ./setup.sh

# and make yourself familiar with the script
./setup.sh help

4. 修改mailserver.env，启用pop3

# 1 => Enables POP3 service
# empty => disables POP3
ENABLE_POP3=1
ENABLE_CLAMAV=0

5. 修改 docker-compose.yml 内容为合适路径（注意目录权限）

version: '3.8'

services:
  mailserver:
    image: docker.io/mailserver/docker-mailserver:latest
    hostname: mail
    domainname: mkplay.xyz
    container_name: mailserver
    env_file: mailserver.env
    # To avoid conflicts with yaml base-60 float, DO NOT remove the quotation marks.
    # More information about the mailserver ports:
    # https://docker-mailserver.github.io/docker-mailserver/edge/config/security/understanding-the-ports/
    ports:
      - "25:25"    # SMTP  (explicit TLS => STARTTLS)
      - "110:110"  # POP3
      - "143:143"  # IMAP4 (explicit TLS => STARTTLS)
      - "465:465"  # ESMTP (implicit TLS)
      - "587:587"  # ESMTP (explicit TLS => STARTTLS)
      - "993:993"  # IMAP4 (implicit TLS)
    volumes:
      - "/data0/Server/Db/mail:/var/mail"
      - "/data0/Server/Var/mail-state:/var/mail-state"
      - "/data0/Server/Logs/mail:/var/log/mail"
      - "/etc/localtime:/etc/localtime:ro"
      - "./config/:/tmp/docker-mailserver/"
    restart: always
    stop_grace_period: 1m
    cap_add: [ "NET_ADMIN", "SYS_PTRACE" ]

6. 试运行

docker-compose up -d mailserver

./setup.sh email add <user@domain> [<password>]
./setup.sh alias add postmaster@<domain> <user@domain>
./setup.sh config dkim

7. 完成
