Mailserver 维护
SSH 配置（IP 不暴露）
容器内 SSH 通过 ~/.ssh/config 连接 cloud：
Host cloudrelay
HostName 101.43.110.225
User administrator
IdentityFile /home/cloudrelay/.ssh/id_rsa
StrictHostKeyChecking=no
BatchMode=yes连接：ssh -F /home/cloudrelay/.ssh/config cloudrelay "..."
启动（DMS Docker）
cd ~/docker-mailserver && docker compose up -d mailserver
docker exec mailserver supervisorctl statusCloud SMTP AUTH Relay（Windows cloud）
# 检查状态
ssh -F /home/cloudrelay/.ssh/config cloudrelay "cmd /c netstat -ano | findstr :2526 | findstr LISTEN"

# 3. SSH 测试
docker exec mailserver ssh -F /home/cloudrelay/.ssh/config cloudrelay echo OK
# 4. 强制重试
docker exec mailserver postqueue -f
