Installing Symantec Encryption Server & Exchange 2010 Configuration Part3–Sending Encrypted Emails


In part1 and part 2 we explored the basics of installing the SES and configuring and managing encryption Keys, in this part we will glue part1 and part2 and send encrypted emails.

Understanding Email Policies:

Email policies are the foundation block for handling email, they determine how emails from specific senders sent to specific recipients with specific contents will be handled.

There are set of defaults policies created by default:

they determine how outbound/inbound emails will be handled, the default policy has the following settings:

the outbound client has the following settings:

which tell the SES to encrypt the emails if the source client is SMTP/MAPI to send it to the outbound chain which does the encryption actions:

if we explore the outbound chain, we will find the following settings:

which instructs the SES how to handle specific emails with specific conditions, so I edited this rule and added the “confidential rule”, which encrypts emails sent internally or externally with the word “confidential” in the subject line. You can add your own set of rules to meet your business and enforce certail delivery types link web or protected PDF:

Once you set the rules, you can send encrypted emails, let us see how:

from outlook client, I will send normal email to user@domain.com (which is fictional domain), the client will detect the policy that is set on the server and will send the email out of message steam to the SES:

Because we can’t find a key for user@domain.com, we will send the email to the SES server and the SES will send the user an email notifying him that there is a message waiting him:

In the above email, I am opening the EML file via notepad (I do have only SMTP server at the recipient side), so the message contains the link to open the email (take a look to how the email flowed from the client to keys “the SES Server” to Exchange to the recipient server)

when opening the link, the client will be prompted with the registration (to register in the SES portal with a passphrase), Then the user can login:

Once user login, he can see the email through the portal; The user can reply and interact securely with the internal user or ask for email delivery via secure PDF:
