Good to hear you found something you like. Zimbra is a good choice and has a lot of features so I don't think you will be disappointed. Scalix and Zimbra compare well on some points and not so well on others (ease of installation) so the needs of the end user determine which tool to go with. Zimbra is easier to install and manage then Scalix but in my experience Scalix scales much better and has better Outlook support. I am very impressed with Zimbra's mashup tools/open API and I think it has a lot of integration possibilities. Scalix is releasing a set of APIs in Scalix 11 that should provide the same capability. Have playing with Zimbra, you will have enjoy the experience.

Ed,
Thanks for your help. I learned a lot yesterday about both applications but in the end I deployed Zimbra. It's supposedly integrated with AD as my tests indicate successful. Still not sure how to use it as I still have to create user id's.
This wasn't really the main factor, it was a nice thing to have. When I deployed scalix the mail didn't work even after creating accounts?
Zimbra did and installed the whole package (amavisd, spamassasin, postfix, imap, etc).
I know Scalix mentions it as a capability but I wasn't sure if this required more configuration as well as other packages...
It was a tough call and I give kudo's to both. Scalix has a nice installer GUI which shows a level of maturity. It also has the ability to start and stop services which I don't think Zimbra can do from the webGUI.
On the other hand Zimbra has some good webGUI queue management tools as well as letting you see what's going on.
In the end the presentation of the user web interface looked a little better to me.
I believe both have a good command line environment.
That's my 60 second take on the matter. I could have missed some things I went back and forth 3 or 4 times yesterday to finalize my decision.
Oh in both cases uninstall was very easy...
thanks,
James

James,
I have bad news for you - the community edition does not support AD integration using the MMC plugin. What you can do is use AD's LDAP interface which the Scalix community edition can use for password authorization. You will have to create email accounts in the Scalix SAC, but all passwords would come from AD.
Thanks
Ed

Ed,
I tried creating an account last evening but never recieved a confirmation email. I do not see the Forest prep tool that they mention. Where is it located? I downloaded my open source distro and looked in the software folder and did not find it.
Thanks,

James,
Looks like you have more then one problem here so I am going start with your AD/SSO integration issue - BTW - have you tried the Scalix Community forum at http://www.scalix.com/commnity? It offers an excellent source of help and many of the Scalix developers and support personal hang out there.
You do need to run Forest Prep in order to integrate Scalix into AD. For Scalix version 10.0.1 go to page 102 of the admin guide and start from there. I am guessing you setup SSO and Kerberos without integrating AD first so Scalix is not recognizing any of your users.
Once you run though the AD integration steps you can get SSO to work. Below is a short version of the instructions that I used. The admin guide includes more detailed instructions. Let me know how it goes.
Ed
For SSO integration with AD - here are the instructions I used to get it working
SSO AD INSTRUCTIONS
Step 1. Make sure you have created Forward Lookup Zones for your domains and created Host records for all Scalix Servers in the appropriate Forward Lookup Zone. Step 2. Under Forward Lookup Zones, select a Scalix Server Single Sign-on domain and go to Action > New Alias. Step 3. Create a new Alias called _scalix-default-mail_ in the Alias name field, and the fully qualified name of the Scalix Server with which you are using Single Signon in the Fully qualified name for target host field (for example, scalixserver.acme.net). Step 4. Create reverse lookup zone for the Scalix server. Step 5. Go to Active directory User and Computers and create a new OU and call it Scalix services. Step 6. Select the Scalix service OU and Action > New > User. Step 7. Create the user, enter _scalix-ual_ in the first name field. You can also enter the name of the Single Sign-on Scalix Server in the Last Name field. This allows you to identify the keytabs you generate for multiple Scalix Servers. Click next and Enter and confirm a password for the user. Make sure that the password you enter is sufficiently complex and that; User must change password at next logon field is not selected User cannot change password field is not selected Password never expires field is selected Click next and clear the create an Exchange mailbox field, then click next and then click finish. The user has successfully been created for the Scalix UAL service. Step 8. Generate a Kerberos keytab, enter:
ktpass _princ scalix-ual/scalixservername.domain@REALM _mapuser scalix-ual -pass password _out path\filename -kvno 3 For example: ktpass -princ scalix-ual/scalixserver.acme.net@ACME.NET -mapuser scalix-ual -pass password -out scalix-ual.keytab -kvno 3 Step 9. Copy the keytab to the home directory of the Single Sign on Scalix Server.
Step 10. Run the command. ommergekeys /path/filename.keytab Where /path is the location that you copied the keytab too.
Step 11. omkrbconf -r REALM -s servername.domain -d domain
-r specifies the realm that the Kerberos database controls. For example, if your domain name is acme.com, your realm is ACME or ACME.NET.
-s specifies the fully qualified host name of the Kerberos KDC machine. For Single Sign-on, the KDC is the Domain Controller with Active Directory installed. Step 12. In order for Single Signon to work , the authentication ID for a scalix server mailbox must match the domain identity (Active Directory ID) for the user. For example, if jsmith@acme.net is the user logon ID for a user in AD then enter the following on the Scalix server:
ommodu _o jsmith -_authid jsmith@ACME.NET
Note: The realm MUST be in uppercase. To view the user; omshowu _Joe Smith/mailnode_
Step 13. Test out the connection. Run the command ; kinit _your AD user ID_ for example kinit jsmith @ACME.NET You should be prompted for your AD password, enter it and it should just come back to you. Step 14. Modify the /var/opt/scalix/sys/pam.d/ual.remote file. The only lines that are needed are these four; auth required om_krb5 user_unknown=ignore auth optional om_auth use_first_pass account required om_auth password required om_auth
Now save that file and now edit the pop3 file and make sure it has the same entries as the ual.remote. Now save that po3 file and edit the omslapdeng file and make sure it has the same 4 entries. Now save the omslapdeng file and edit the smtpd.auth file and make sure it has the same 4 entries. Now save that file and we are done.
TESTING. You can now log onto scalix using your AD logon credentials. Log into SWA via your AD id and AD password to test. To Test Outlook, create a new profile and enter in the scalix-default-mail as the server and that should automatically finish.

Ed,
I saw no activity though the sac queue (I kept refreshing) but no luck. I had created 2 users in SAC to hopefully catch all of the mail that I was no longer recieving while I was trying to get the kerberos going... I believe what could have been the cause is: 1 the post I read on setting this up wasn't correct or some part of the process was not the same 2) I configured scalix to authenticate against the kerberos. So when I tried to logon I kept getting rejected as password or userid not found 3) not understanding what I am getting -> do I have to create an account and 'tie' it to the kerberos?
The sendmail was rejecting to my userid even though the user existed on both the sac and AD, which supports my idea that it's not 'authenticating' with the AD server...
As I mentioned sendmail isn't my favorite but I did run for some time before moving to postfix. From what I've read scalix takes care of this. Are there any post install scalix scripts that I have to run?
I see that there is a component called Scalix ForestPrep. Is this included in the open source distro? I would prefer this if possible. A single sign on is ok if that's all I can get but having true integration with the directory server would be preferable as I would like to have a single entry for ease of admin.

James,
When you say mail is not coming in do you mean that scalix is not accepting mail for your users? Did you provision your users in the Scalix SAC? What sort of error message is Scalix giving you when it rejects email?
Also, sendmail is most likely not the issue as sendmail is only used to process outbound mail. Scalix has its own smtpd that handles processing inbound mail and relaying. Let me know if I can help.

Easy for you to say! I was up late last night trying to figure out why no mail was coming in? I think it has to do with the kerberos integration with AD (which is what provides the single sign on).
I followed the directions and even saw users but for the life of me I could not logon to webmail?
Using the sxadmin I noticed that no mail was active at all in the queue? Do you have any idea to what could be the cause?
All of the mail coming in was being flat out rejected. Was there some additional steps that had to be done on 'sendmail' I had not configured the sendmail.mc which I would have typically done to get a mail server running with sendmail.
I hate sendmail (though I have a big hefty sendmail book) and moved to postfix for the ease of admin...
Perhaps I do not understand what is going on with the imap service and mta. I noticed that there is a modififed sendmail.cf that contains information of scalix. This makes me think that scalix 'should' (key word) be setting up what it needs to. By default sendmail will only accept mail from localhost. Does scalix take care of this or is it one more thing that I have to do? The docs and knowledge base do not really talk about it, which makes me believe that this thing should be working out of the box.
I would like to give another shot (this time try it without the AD intergration) to see how it works.
Thanks,
James

Extremely easy if you have the right RPM andright OS, just RH [CentOS] or SUSE. Disable your existing postfix..., they provide everything.
I just changed from a linux Samba DC to an Active Directory one to change things up a bit. Does this Zimbra integrate with AD (or vice-a-versa)?
No experience, my customers do not have ADs, but Zimbra claims easy integration. Take a look @ http://www.zimbra.com/forums/showthread.php?t=1614 and http://www.google.ca/search?q=zimbra+active+directories
