我在 postfix/dspam/dovecot 配置中遇到了这个问题：
May 28 12:35:59 mx01 dspam[1514]: Creating local domain socket /var/spool/postf
ix/dspam/dspam.sock
May 28 12:35:59 mx01 dspam[1514]: Daemon mode failed to start
May 28 12:35:59 mx01 dspam[1514]: Daemon process exiting
这是我的 /etc/postfix/master.cf：

解决了。错误配置是在 dspam.conf 文件中，这里是正确的配置：
