Comment 3 for bug 1252441

Given that I use postgrey on my servers, and that I will upgrade to 14.04 LTS when it comes out, I decided to try some preventative maintenance and see if postgrey is really broken on 13.10.

I was unable to reproduce your problem:

    $ sudo apt-get install postgrey

    $ ps $(cat /var/run/postgrey.pid)
      PID TTY STAT TIME COMMAND
    17720 ? Ss 0:00 /usr/sbin/postgrey --pidfile=/var/run/postgrey.pid --daemonize --inet=10023

    $ sudo lsof -i TCP:10023
    COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
    /usr/sbin 17720 postgrey 6u IPv4 2248799 0t0 TCP localhost:10023 (LISTEN)

    $ less /var/log/syslog

Hm.
