postfix和spampd使用相同的端口（ISPConfig和Ubuntu）

Question

仅安装了最新的ubuntu服务器以及ISPConfig和smtp（后缀未启动）

 postfix/master[30556]: fatal: bind 127.0.0.1 port 10025: Address already in use

所以我检查了端口10025，发现spampd已使用它：

fuser -uv  10025/tcp
                     USER        PID ACCESS COMMAND
10025/tcp:           spampd     7988 F.... (spampd)spampd
                     spampd     7990 F.... (spampd)spampd
                     spampd     7994 F.... (spampd)spampd
                     spampd     7995 F.... (spampd)spampd

任何解决方案如何使其协同工作？
