I have been using the squeeze perfect server. http://www.howtoforge.com/perfect-server-debian-squeeze-with-bind-and-dovecot-ispconfig-3-p3 This server has been great. My only problems are associated with updating freshclam and webmail. I like the debian as a server even though I have spent more time using SUSE and OpenSuse. Opensuse seems to have the most up to date tutorial but could possibly have more bloat. My vps may be on the fritz so there may be a new load/upgrade or other in my future. I have an older verison of IPSconfig so at the very least I am do for an upgrade. Can I fix the email issues via simple upgrade? If I decide to build another server which one should I try and will the email be any easier to administer.
