Multi Tenant Email Server Configuration

Multi Tenant Email Server Configuration

In this tutorial I am going to explain how to host multiple email domains on one Domain controller and Exchange server. 

Say for example , A company have two Branches and they are namely Dandenong and Mulgrave. The company doesn't want to have common email address. They want to have emails specifically branches 

So the users in Dandenong will have their mail address as user@dande.mks.com.au and the user in Mulgrave will have user@mul.mks.com.au. We can do the same to even different domains , Lets see how we can do this...

First of all to do this we need to have UPN ( user principle names ) and OU ( organizational units ) to create emails and user account. Lets see how we can do this 

Create OUs

1.    . Navigated to ‘Active Directory Users and Computers’ and created OUs for Dandenong and Mulgrave:

2.    Created two users in each OU, Mulgrave One and Two for the Mulgrave OU, and Dandenong One and Two for the Dandenong OU:

       Create UPNs: 

       Navigated to ‘Active Directory Domains and Trusts’:

           Right-clicked ‘Active Directory Domains and Trusts’ and selected ‘Properties’. Added ‘mulgrave.mks.com’ and ‘dandenong.mks.com’ as alternate UPN suffixes and clicked ‘Apply’ and ‘OK’:

       On the Exchange server : 

   Navigated to ‘Accepted Domains’ and added the        ‘dandenong.mks.com’ and 'Mulgrave.mks.com' UPN as an accepted        domain on the Exchange server:

Create Email Policy     

Navigated to the Exchange Administration Centre, and went to ‘Mail Flow > Email Address Policies’:

     Under ‘Email Address Format’, changed the address format to      ‘dandenong.mks.com’

Under ‘Apply to’, added a new rule and selected ‘Recipient Container’. Selected the previously created ‘Dandenong’ OU and clicked ‘Save’

Created a new email policy named ‘Mulgrave’ and repeated Steps for the ‘Mulgrave’ OU:

Created Users Email

     Navigated to ‘Recipients’ on the Exchange Admin Centre and added the Dandenong One, Dandenong Two, Mulgrave One and Mulgrave Two users from the OUs previous created:

   Noted that each user had the proper sub-domain applied as their email address, so the Email Policies had been applied successfully:

Configuring VoIP Basic level Packet Tracer

Configuring VoIP  Basic level Packet Tracer

Cisco Unified Call Manager Express to configure a basic VoIP. 

So the first thing to be done is to configure the IP address of the router:

Router>enable

Router#configure terminal

Router(config)#interface FastEthernet0/0

Router(config-if)#ip address 192.168.100.1 255.255.255.0

Router(config-if)#no shutdown

A DHCP server is used to assign IP addresses to the IP Phones.

A TFTP server is used to allow the phones to get the firmware and certain configurations files from the router, this is done by the option 150 of the DHCP.

Router(config)#ip dhcp pool VOICE

Router(dhcp-config)#network 192.168.100.0 255.255.255.0

Router(dhcp-config)#default-router 192.168.100.1

Router(dhcp-config)#option 150 ip 192.168.100.1

Next step to do is to configure the Call Manager Express itself on the router

Router(config)#telephony-service

Router(config-telephony)#max-dn 5

Router(config-telephony)#max-ephones 5

Router(config-telephony)#ip source-address 192.168.100.1 port 2000

Router(config-telephony)#auto assign 1 to 5

1. Enters to the telephony services, if you don't have the telephony-service you have to enable by      typing the following in 2911 serious router. 

Note: license boot module c2900 technology-package uck9 

2. max number of phone lines

3. max number of telephones

4. The IP of the router, this is where the telephones will be registered and the source address where is running the DHCP and TFTP services, which will be the router itself. And the port used for the phones, the default one is 2000

5. This is to automatically register the phones, on this case is from phone 1 to 5 

Router(config)#ephone-dn 1

Router(config-ephone-dn)#number 100

Router(config)#ephone-dn 2

Router(config-ephone-dn)#number 200

Router(config)#ephone-dn 3

Router(config-ephone-dn)#number 300

Router(config)#ephone-dn 4

Router(config-ephone-dn)#number 400

Router(config)#ephone-dn 5

Router(config-ephone-dn)#number 500

We have configured 5 max IP Phones, so we will configure 5 max numbers for the line, 

Now thats all on the router, we have to configure the switch to access Voice VLAN. 

Switch(config)#int range fastEthernet 0/2-3

Switch(config-if-range)#switchport mode access

Switch(config-if-range)#switchport voice vlan 1

Interface 1 I have configured as Trunk interface 

Switch ( config) #int fastEthernet 0 /1

Switch(config-if)#switchport mode trunk 

If the encapsulation is Dot1q then just leave it as it is

That is all , now we must have our Phones configured with the numbers we have configured above
