Well, I stumbled onto zimbra.... I have a Scallix system built, but still have some rough edges to try to smooth. Like the way it works with sendmail, no dnsbl's will work as sendmail sees all mail as coming from locohost (scalix). Still battling that one which is when I ran across Zimbra. So, this made me start wondering. Are there other exchange server-like products out there? Has anyone dealt with Scalix and Zimbra (or another from the question above) and would you care to post pros and cons to each? Some of the cons to me with Scalix. It uses it's own directory structure which is non-sensical to any admin. Each seems to be assigned on a numbering system.. finding who has what where is not fun and I fear will be a nightmare in the future. Sendmail milters work fine to a point, but there is the limit of filtering using dnsbl's and it appears it will require setting up sendmail as the receiver, passing to scalix, passing back to sendmail, passing back to scalix and the user mail boxes... adding an extra loop. Shared folder are nice.. shared calendars are pretty good although I don't see a way to sort by user are even really see immediately for which user the event exists. You can drag and drop from Outlook IMAP a file directly to the server, but internally we don't use outlook... but for other clients this could be nice. So, how are those Zimbra installs going and what's the scoop? Thanks, John Hinton
Open-Xchange is a nice one, It could be painfull to install so I have put together a CD, based on CentOS 44 with OX and lost more, you will be up and running in about 30 minutts You may find more information on my website http://www.nnortux.no Click on the flag to get some information in english I have made one with CentOS 5 allso, but at the moment, my impression is that CentOS 5 is a bit inmature, lots of the modules dont work, so until I got all modules working try it with CentOS 4.4 Enjoy Tronn On 8/31/07, John Hinton <webmaster at ew3d.com> wrote:> > Well, I stumbled onto zimbra.... > > I have a Scallix system built, but still have some rough edges to try to > smooth.

They didn't experiment with the standards, so you will fell comfortable administering the machine. Regards, -- Tomasz Napierala System Administrator Allegro Team http://www.allegro.pl/

Hi John, On Fri, 2007-08-31 at 16:27 -0400, John Hinton wrote:> Well, I stumbled onto zimbra....I tried the demo a long time ago when it was first launched.

Still battling > that one which is when I ran across Zimbra.A while back I was investigating Scalix. There are documents on the Scalix wiki that explain how to use postfix instead of sendmail: http://www.scalix.com/wiki/index.php?title=HowTos/Postfix http://www.scalix.com/wiki/index.php?title=HowTos/Complete_Postfix> So, this made me start wondering. > > Are there other exchange server-like products out there?I'm only aware of the ones already mentioned by others. Obviously there are commercial alternatives like Kerio.> Has anyone dealt with Scalix and Zimbra (or another from the question > above) and would you care to post pros and cons to each?Nope, I have no experience with either apart from looking at the Scalix docs and the Zimbra demo.> Some of the cons to me with Scalix. > > It uses it's own directory structure which is non-sensical to any admin. > Each seems to be assigned on a numbering system.. finding who has what > where is not fun and I fear will be a nightmare in the future.Doesn't sound very manageable. Here is a link to a doc explaining howto use an already deployed openldap server: http://www.scalix.com/wiki/index.php?title=HowTos/OpenLDAP_User_Management Quess it should also be possible to use the Red Hat/Fedora Directory Server and iirc there is also a doc about Scalix and Active Direcory. See the howto section on the Scalix Wiki.> Sendmail > milters work fine to a point, but there is the limit of filtering using > dnsbl's and it appears it will require setting up sendmail as the > receiver, passing to scalix, passing back to sendmail, passing back to > scalix and the user mail boxes... adding an extra loop.See what you mean. I'd replace sendmail with postfix any day.> Shared folder are nice.. shared calendars are pretty good although I > don't see a way to sort by user are even really see immediately for > which user the event exists. > You can drag and drop from Outlook IMAP a > file directly to the server, but internally we don't use outlook... but > for other clients this could be nice. > > So, how are those Zimbra installs going and what's the scoop?Found a few links comparing Zimbra, Scalix and Open-Xchange: http://www.linuxjournal.com/article/8722 http://www.dotmedia.co.za/web/opensource/mail-collaboration/ http://forums.whirlpool.net.au/forum-replies-archive.cfm/730879.html (look for the post from MistaKa0s) http://techrepublic.com.com/2415-1035_11-92919.html http://downloads.techrepublic.com.com/abstract.aspx?docid=302289 http://www.open-xchange.org/cgi-bin/simpleforum.cgi?fid=01&topic_id=1143150870 (look for the post from Paul Sterne and BoP) Regards, Patrick
