Encrypt SMTP mail

Hi,

I am going to implement security for smtp mail in my organisation. For encrypting mail going through smtp for the recipient only.

I could use “normal” notes encryption but in some cases we need to send mail via smtp.

How do I encrypt those messages for the recipient only ? I know domino quite well, but I have never looked at it in this way before…

Is there anyone who can help me on the right track here ? maybe kind of step-by-step guide ?

I have read a bit about S/MIME that I think I need to use, but I can not get quite hold of what to to…

Suggestions will be appreciated…

Regards

Roger Hansen

If you’re looking to implement a way for Notes Users to Encrypt Mail, see the Lotus Administrator Help Database topic “Mail encryption”. Essentially here is what the Notes Users would need to Encrypt Mail:Lotus Notes clients need the following to send encrypted messages:

The recipient’s Internet certificate stored in Contacts, the IBM® Lotus® Domino®, Directory, or LDAP directory. If the Internet certificate is stored in a Lotus Domino Directory in another domain or in an LDAP directory, the directory needs to be accessible using directory assistance.

A cross-certificate issued for either the recipient or the CA that issued the recipient’s Internet certificate. This cross-certificate must be stored in the client’s Personal Address Book.

Note It is not necessary to have the cross-certificate prior to sending S/MIME encrypted mail. Users will be prompted to generate the cross-certificate when they try to send the message.

Who/what will you use as a Certificate Authority to issue the Internet Certificates? A 3rd-party source or Domino?

In addition, perhaps the transmission of the message should also be encrypted. Here’s a great TechNote on configuring SMTP to use SSL, encrypting the transmission of the message to the recipient’s MX host:
