I just checked my system with nmap, and it returned two open ports that I don't know what they are for...
Port 587: submission
port 2000: callbook
What are they for, should they be open?

port 587 seems to be ESMTP, a port probably opened by sendmail.  http://www.armware.dk/RFC/rfc/rfc2476.html  I'd guess it should be open if you think port 25 should be open.

I've no clue what callbook is, but it's perhaps related to ham radios?  Here's a few related pages (search for callbook within them)
