SSL Decryption
In order to perform SSL decryption, the certificate and the private key used for the virtual server created earlier must be imported into Virtual Traffic Manager.
1. Select Catalogs > SSL > SSL Certificates.
2. Click Import Certificate to import the appropriate certificate.
After importing the certificate, enable SSL decryption on the virtual server created:
1. Select Services > Virtual Servers, and select the virtual server that will be performing SSL decryption.
2. Scroll down and click SSL Decryption.
3. Set ssl_decrypt to Yes.
4. Select the certificate imported earlier.

Configuration Summary
By accessing the Services > Config Summary on the WebGUI, a complete snapshot of all configured services is provided. This is a very useful table to glance through to get a good understanding of how the services are configured.
Configuration Steps for IMAP4 and POP3
IMAP4 and POP3 services on Exchange 2013 enable mail clients that support IMAP4 and POP3 protocols to access the
Exchange 2013 CAS server running IMAP4 and POP3 services. By default, these services are disabled in Exchange 2013. To support these protocols, IMAP4 and POP3 services should be enabled.
For more information about how to manage and configure POP3 and IMAP4 in Exchange 2013, see POP3 and IMAP4 on
Microsoft TechNet at http://technet.microsoft.com/en-us/library/jj657728(v=exchg.150).aspx

Component Procedure Description
Virtual Traffic Manager
(once for each service)
Create a traffic IP group for POP3 and IMAP4 services. A traffic IP group must be created on which a virtual server
listens. For details, see the “Creating a Traffic IP Group”
section.
Virtual Traffic Manager
(once for each service)
Create a pool for POP3 and IMAP4 services. A pool must have a set of servers to load-balance. Enter the host name or IP address of the node along with the
TCP/UDP port. For details, see the “Creating a Pool”
section.
Virtual Traffic Manager
(once for each service)
Create a virtual server for POP3 and IMAP4 services.
Virtual Traffic Manager
(once for each service)
Configure SSL decryption for POP3 and IMAP4 services.
Create and associate the virtual server to the server pool.
For details, see the “Creating a Virtual Server” section.
Configure SSL decryption to enable SSL offloads. For
details, see the “SSL Decryption” section.

Creating a Traffic IP Group
Create a traffic IP group (also known as a virtual IP) on which the virtual server will listen. To create a new traffic IP group:
1. Select Services > Traffic IP Groups, and scroll down to Create a new Traffic IP Group.
2. Enter the following:
•
Name: A descriptive name for the POP3 and IMAP3 pool, assuming that the POP3 and IMAP4 FQDN resolves to the same traffic IP group (e.g., pop.company.com)
•
IP Addresses: An IP address that will be associated with the FQDN of the POP3 and IMAP4 service
3. Click the Create Traffic Group button.
Creating a Pool
A pool must be created for each service that is managed by the Virtual Traffic Manager. To create a new pool:
1. Select Services > Pools and scroll down to Create a new Pool.
2. Fill in the fields as follows:
•
Pool Name: A descriptive name for the pool
•
Nodes: hostname:110 or ipaddress:110
•
Monitor: POP
3. In the next screen, click Load Balancing.
4. Under Algorithm, select Perceptive.
5. Click the Update button to apply changes.
Repeat Step 1 through Step 5 to create a new pool for IMAP4 using port 143 for the Nodes.
For IMAP4, the health monitor should be a TCP transaction monitor. Perform the following steps to create a new health monitor:
1. Select Catalogs > Monitors > Create New Monitor. Type a name, and select TCP Transaction Monitor.
2. Use the following values for parameters:
• close_string: logout\r\n
• delay: 10
• response_regex: \* OK.*
• timeout: 10
3. Select Services > Pools, and under Health Monitoring, choose the created monitor.
Create a Virtual Server
Create a virtual server to handle all the traffic. To create a new virtual server:
1. Select Services > Virtual Servers, and scroll down to Create a new Virtual Server.
2. Enter the following:
• Virtual Server Name: A descriptive name for the virtual server
• Protocol: POP3
• Port: 995
• Default Traffic Pool: The pool created earlier
3. Click Create Virtual Server.
