1. docker + email

docker pull lejmr/iredmai:mysql-lastest
docker run -d --privileged -p 90:80 -p 8443:443 \
           -e "DOMAIN=snowdreams1006.cn" -e "HOSTNAME=mail" \
           -e "MYSQL_ROOT_PASSWORD=123456" \
           -e "SOGO_WORKERS=1" \
           -e "TIMEZONE=Europe/Prague" \
           -e "POSTMASTER_PASSWORD=123456" \
           -e "IREDAPD_PLUGINS=['reject_null_sender', 'reject_sender_login_mismatch', 'greylisting', 'throttle', 'amavisd_wblist', 'sql_alias_access_policy']" \
           -v `pwd`/mysql:/var/lib/mysql \
           -v `pwd`/vmail:/var/vmail \
           -v `pwd`/clamav:/var/lib/clamav \
           --name=mail lejmr/iredmail:mysql-latest

scp /Users/snowdreams1006/Downloads/docker-compose.yml root@snowdreams1006.cn:/root/mail

docker-compose -f docker-compose.iredmail.yml up -d

docker-compose.iredmail.yml

mail.snowdreams1006.cn/iredadmin/dashboard/checknew

1.9. 启动容器

docker run  -d -h mail.snowdreams1006.cn --restart=always \
      -p 25:25 \
    -p 587:587 \
    -p 465:465 \
    -p 143:143 \
    -p 993:993 \

    -v `pwd`/ssl/dkim/:/ewomail/dkim/ \
  --name ewomail bestwu/ewomailserver

2. 进入虚拟机

docker exec -it ewomail /bin/bash

3. 在/etc/hosts中已有域名指向

172.17.0.2 mail.snowdreams1006.cn mail

  • sendmail:用于发邮件。资格最老的邮局,所有Linux发行版基本都带。但是配置麻烦。
  • postfix:Wietse Venema觉得sendmail配置太麻烦了,就开发了一个“简化配置版sendmail”,即postfix。支持smtp协议。
  • dovecot:用于收邮件,支持imap/pop3。
  • spamassasin:垃圾邮件过滤器。可以自订规则。
  • clamav:邮件杀毒工具。
  • opendkim:生成dkim签名。有什么用?详见下面的“反垃圾邮件技术”。
  • fail2ban:防止别人暴力破解用户名密码的工具。

3.1. 配置

运行成功后访问

默认用户: admin

默认密码: ewomail123

ewomail.snowdreams1006.cn

rainloop.snowdreams1006.cn/?admin

默认用户: admin

默认密码: 12345

rainloop.snowdreams1006.cn

3.2. 设置域名DNS

将mail.ewomail.cn 改成你的域名

v=spf1 include:snowdreams1006.cn -all

3.3. dkim 设置

docker exec ewomail amavisd showkeys
docker exec ewomail amavisd testkeys
docker pull tvial/docker-mailserver:latest
curl -o setup.sh https://raw.githubusercontent.com/tomav/docker-mailserver/master/setup.sh; chmod a+x ./setup.sh
