Exchange to ZCS Migration

[shrry8]

Hey,

I am planning to migrate to RHEL 5.1 with ZCS as my email server currently i using MS-Exchange 2003
Rest of my Network will be on Microsoft Platform except Email Server.

I want to know wheather i can use existing Active Directory logins and groups to autheticate user for accessing ZCS emails.

secondly, i have created a fresh machine with RHEL 5.1. The name of the machine is "navigator". I want to make my users email as username@mycompany.org can i do that i dont want username@navigator.mycompany.org


thirdly, i did configure SENDMAIL Server to check my abilities and i did that pretty fine. If i turn off SENDMAIL then do i need DNS Entries so that ZCS would work. I AM CURRENTLY USING DNS ON WINDOWS PLATORM.


last, my mail server will not be directly connected to internet for external email routes. what will be the best solution if i want to route my emails to another server which do have an Internet connection.


Suggestions will be welcomed

Admin console > Domain > Configure Authentication wizard:


You'll want to configure the GAL for 'both' as well.

LDAP Authentication - Zimbra :: Wiki

Via CLI you'd need to set the zimbraAuthMech the domain.

You can create accounts like the below when you don't want them to authenticate internally:
zmprov ca user@domain.com ‘’

If you do assign passwords:
zmprov ca user@domain.com password
While external auth those passwords still aren't used unless you turn on:
zmprov md domain.com zimbraAuthFallbackToLocal TRUE

Admin accounts in the most recent versions automatically have fallback auth 'set' in-case your external LDAP/AD auth is unavailable or configured improperly.

Just create another domain in the admin console/JAVA/SOAP/CLI wrapper etc:
su - zimbra
zmproc cd domain.com
zmprov mcf zimbraDefaultDomainName domain.com (so you don't have to type @domain.com for login - if you have more than 1 domain that you want quick login for then set virtual hosts on each in admin console > domain > virtual hosts)

The ZCS box shouldn't have sendmail running on it - by default you're going to conflict with postfix:
chkconfig sendmail off
service sendmail stop

As you're not connecting this to the internet your not completely doing a split dns for the ZCS box, but it does need to resolve itself on the internal LAN (via your windows DNS or you could run Bind on the ZCS box itself to accomplish that.

Admin console > Global or Server > MTA > Relay
CLI: zmprov ms server.domain.com zimbraMtaRelayHost external.relay.com:#

If you need auth: Outgoing SMTP Authentication - Zimbra :: Wiki

If you're not going to migrate everyone at once: Split Domain - Zimbra :: Wiki

The Exchange Migration tool is located on your ZCS server via the admin console link or at: http:// server.domain.com/downloads/index.html

If you hit an "Appointment with Uid[]" warning you can grab this tool: [SOLVED] PST Import Tool "Appointment with Uid[]..." warning

Can you please elaborate this line in detail, its from Split DNS

3. Create a /var/named/db.server.example.com zone file. (If named runs in a chroot'ed directory /var/named/chroot, db.server.example.com should be placed in /etc/named/chroot/var/named/db.server.example.com and you should create a symbolic link to /var/named/db.server.example.com.)

i have both the directory ony my Fedora 9 Machine
/var/named/
/var/named/chroot

I have created named.conf file in /etc/named.conf

where to create db.server.example.com zone file
and how to create symbolic link ... i dont know that
