Certain Services Down

[Stevanicus]

I see that no-one was able to help me with my previous thread so here is new one with the only issues I am currently facing.

I have the following services that are down and wonder how I can get them running again and how I find out why they are working?!

Code:

localhost   (Port 9876)      ispCP Daemon      UP
      localhost   (Port 10024)     AMaVis     DOWN
      192.168.1.66   (Port 53)     DNS     UP
      192.168.1.66   (Port 21)     FTP     UP
      192.168.1.66   (Port 80)     HTTP     UP
      192.168.1.66   (Port 143)     IMAP     UP
      localhost   (Port 12525)     POLICYD-WEIGHT     UP
      192.168.1.66   (Port 110)     POP3     UP
      192.168.1.66   (Port 995)     POP3-SSL     DOWN
      localhost   (Port 60000)     POSTGREY     DOWN
      192.168.1.66   (Port 25)     SMTP     UP

      localhost   (Port 783)     SPAMASSASSIN     DOWN

Thanks in advance
