Hi! I just couldn't avoid reading this post.
I actually make a live out of replacing MS solutions with Open Source-based solutions. I know, it is not perfect, and there are some features that you will not get, but in my experience these features are not used very often. Anyway, I would give a try to egroupware: Postfix + Dovecot + eGroupWare + LDAP That combination has worked very well for me. Off course, you could, in theory, use Active Directory for the LDAP (after all, on of AD's piece is a LDAP server), but I hasn't done that myself yet. I hope this helps, Ildefonso Camargo On Thu, Sep 11, 2008 at 11:57 AM, dnk <[EMAIL PROTECTED]> wrote: > >> As per the subject, I am about to pitch the idea of dumping >> Exchange >> and moving to Postfix.
