环境

Debian 11 Bullseye/sid

安装

官方文档比较详细，建议参考：https://docs.iredmail.org/index.html

特殊事项

1、邮件附件大小更改，文档：https://docs.iredmail.org/change.mail.attachment.size.html

2、SSL证书，采用自签证书

3、对接域控，对接域控邮箱字段 ProxyAddresses (此处为特殊情况，默认非此字段，默认字段已被外部邮箱使用)，参考文档：https://docs.iredmail.org/active.directory.html

其中特殊相关配置文件如下：
