    proxy_connect_timeout 10s;
    proxy_timeout 600s;

    server {
        listen 25;
        proxy_pass mail_smtp;
    }

    # SMTPS (SSL pass-through)
    server {
        listen 465;
        proxy_pass mail_smtps;
    }

    # Submission
    server {
        listen 587;
        proxy_pass mail_submission;
    }

    # IMAP
    server {
        listen 143;
        proxy_pass mail_imap;
    }

    # IMAPS
    server {
        listen 993;
        proxy_pass mail_imaps;
    }

    # POP3
    server {
        listen 110;
        proxy_pass mail_pop3;
    }

    # POP3S
    server {
        listen 995;
        proxy_pass mail_pop3s;
    }

    # Upstream definitions
    upstream mail_smtp       { server 192.168.22.2:25; }
    upstream mail_smtps      { server 192.168.22.2:465; }
    upstream mail_submission { server 192.168.22.2:587; }
    upstream mail_imap       { server 192.168.22.2:143; }
    upstream mail_imaps      { server 192.168.22.2:993; }
    upstream mail_pop3       { server 192.168.22.2:110; }
    upstream mail_pop3s      { server 192.168.22.2:995; }
}

3、配置aliyun的域名解析

必须设置mail-A及@-A记录，否则会导致无法收到邮件。
