Practical solutions for connections administrators
Zimbra set up
1. Installing And Configuring Zimbra Mail Server
First we need to install Sysstat and GMP
Sysstat
A common task for System Administrators is to monitor and care for a server. That's fairly easy to do
at a moment's notice, but how to keep a record of this information over time?
your server is to use the Sysstat package.Sysstat is actually a collection of utilities designed to collect
information about the performance of a linux installation, and record them over time.
GMP
The library gmp provides the extended arithmetic for the number types
2. Stop other mail servers
Chkconfig sendmail off
To turn off sendmail automatically after reboot.
Service sendmail stop
To stop sendmail…otherwise it will conflict with zimbra mail server
3. Then go to System -> Administration and change the DNS settings.
Install webmin and logon to it using web browser
5. Create forwarding and Reverse zone
Creating a Mail Server Record ( MX Record )
Go to the Forwarding Zone that we created and select “Mail Server”
Creating Address Records
Go to “Address” and set "Priority” “Name” and “Address” for an Address Record.
6. Now our DNS server is UP. Go to BIND DNS Server and Restart the BIND ( Stop and Start
DNS again ). Then we have to configure 2 Configuration Files.
Configure “/etc/hosts” file
Change it as follows
11. For large email transfers - zmprov mcf zimbraMtaMaxMessageSize 10240000
Activate Instant Messenger - zmprov mc default zimbraFeatureIMEnabled TRUE
Activate Instant Notifications - zmprov mc default zimbraFeatureInstantNotify TRUE
After that type “exit” and Reboot the server
Now you can login to “Zimbra Admin Server and create accounts
