The software consists of both client and server components, and a desktop client. Two versions of Zimbra are available: an open-source version and a commercially supported version ("Network Edition") with closed-source components such as a proprietary Messaging Application Programming Interface connector to Outlook for calendar and contact synchronization.
The ZCS Server uses open source projects such as:
- Postfix
- MariaDB (since version 8.5)
- OpenDKIM (since version 8.0)
- OpenLDAP
- Jetty (since version 5)
- Lucene
- ClamAV
- SpamAssassin
- Amavis (amavisd-new)
- DSPAM (deprecated starting 8.7)
- Aspell
- nginx (since 5.0)
Prerequisite:
2 GHz 64 bit CPU
Minimum 8 GB RAM
Minimum 10 GB disk
Configure Hostname
Edit /etc/hosts and add the line 192.168.0.25 mail.serverkaka.com mail. Change 192.168.0.25 with the Local IP you want to use.
root@mail:~# cat /etc/hosts
127.0.0.1 localhost
192.168.0.25 mail.serverkaka.com mail
Also edit /etc/hostname and the line 'mail'
root@mail:~# cat /etc/hostname
mail
Reboot the system and test the FQDN of your server with the command hostname -f and hostname.
root@mail:~# hostname -f
mail.serverkaka.com root@mail:~# hostname
mail
Before Zimbra installation, we have to set up DNS configuration (A record and MX Record).
A Record
| Type | Host | Points to | TTL |
| A | 34.73.91.19 | 1 Hour |
MX Record
| Type | Host | Points to | Priority | TTL |
| MX | @ | mail.serverkaka.com | 10 | 1 Hour |
Don't forget to change above value with actual value.
