How do I install a trusted root certificate on my Mac? September 8, 2007 / Dave Taylor / Mac & MacOS Help / 7 Comments I keep getting errors about not being able to establish a secure connection with my mail server in Entourage because of a bad root certificate. DoD ECA certificates integrate seamlessly with a variety of email products including: Microsoft® Outlook; Microsoft® Outlook for Mac; Mozilla® Thunderbird; IBM® Lotus Notes Mail; Apple® Mail; There are several DoD ECA certificate options that can be used for secure email.
In the Keychain Access app on your Mac, choose Keychain Access Certificate Assistant Request a Certificate From a Certificate Authority. Enter your email address, name, and the email address of the certificate authority you want to issue you the certificate, then click Continue. To change the way key pairs are generated, click “Let me specify the key pair information.”.
Mail User Guide
Email messages that are digitally signed or encrypted can offer enhanced security when sending or receiving email.
Send digitally signed and encrypted emails
A digitally signed message lets your recipients verify your identity as the sender; an encrypted message offers an even higher level of security. To send signed messages, you must have a personal certificate in your keychain. To send encrypted messages, the recipient’s certificate must be in your keychain.
In the Mail app on your Mac, choose File > New Message.
Move the pointer over the From field, click the pop-up menu that appears, then choose the account for which you have a personal certificate in your keychain.
A Signed icon (containing a checkmark) in the message header indicates the message will be signed when you send it.
Address the message to recipients.
An Encrypt (closed lock) icon appears next to the Signed icon if your keychain contains a personal certificate for every recipient; the icon indicates the message will be encrypted when you send it.
If you don’t have a certificate for every recipient, you must send your message unencrypted. Click the Encrypt icon to replace the closed lock icon with an open lock icon.
Some mailing lists reject digitally signed messages because the signature is treated as an attachment. To send the message unsigned, click the Signed icon in your message; an x replaces the checkmark.
Note: If for some reason your certificate isn’t associated with your email address, or if you want to use your certificate with a different email address, Control-click the certificate in Keychain Access, choose New Identity Preference, and provide the requested information.
Receive digitally signed and encrypted emails
In the Mail app on your Mac, a Security field in the header area indicates whether a message is signed or encrypted.

A signed icon (a checkmark) appears in the header area of a signed message. To view the certificate details, click the icon.
If the message was altered after it was signed, Mail displays a warning that it can’t verify the message signature.
A lock icon appears in the header area of an encrypted message. If you have your private key in your keychain, the message is decrypted for viewing. Otherwise, Mail indicates it can’t decrypt the message. See If Mail can’t decrypt emails.
Dhs Outlook Email
If you want to include encrypted messages when you search for messages in Mail, set the option in the General pane of Mail preferences. The option enables Mail to search individual words, even though the message is stored encrypted.
