Gitlab重定向网络邮件

Question

我已经配置了gitlab，并将gitlab指向http://gitlabdomain.com地址。我明白了，gitlab也会重定向我的其他域名网络邮件。所以现在，我的webmail.anotherdomain.com无法正常工作，因为它重定向到http://gitlabdomain.com

我使用Plesk。我现在该怎么办？

这是我的gitlab.rb。

import java.io.BufferedReader;
import java.io.InputStreamReader;

    public static void main(String[] args) throws Exception{

        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        Long times = Long.valueOf(in.readLine());

        while(times --> 0){
            long[] pair = Stream.of(in.readLine().split(" ")).mapToLong(Long::parseLong).toArray();
            long mod = pair[1];            
            long[] numbers = Stream.of(in.readLine().split(" ")).mapToLong(Long::parseLong).toArray();
            printMaxMod(numbers,mod);
        }
    }

        }

            }
            Long newMax = (currentNumber - ceiling + mod);
            maxSoFar = maxSoFar > newMax ? maxSoFar :newMax;
            set.add(numbers[i.intValue()-1]);            
        }

        System.out.println(maxSoFar);

    }
