This article describes some areas to troubleshoot PGP Messaging on a Mac.



By default, PGP Desktop automatically determines your email account settings and creates a PGP Messaging service that proxies messaging for that email account.

Because of the large number of possible email account settings and mail server configurations, on some occasions a messaging service that PGP Desktop automatically creates may not work properly.

If PGP Desktop has created a messaging service that is not working right for you, one or more of the following items may help correct the problem:


  1. Verify that you can both connect to the Internet and send and receive email with PGP Services stopped. To do this:
  • Hold down the Option key and select Quit from the PGP Desktop icon in the Menu bar.

    Note: You should always restart your email client after starting or stopping PGP Services.

  1. Read the PGP Desktop Release Notes for the version of PGP Desktop you are using to see if your problem is a known issue.

  2. Make sure SMTP authentication is enabled for the email account (in your email client). This is recommended for PGP Desktop to proxy your messaging. If you only have one email account and you are not using PGP Desktop in a PGP Universal Server-managed environment, then SMTP authentication is not needed. It is required when using a PGP Universal Server as your SMTP server, or when you have multiple email accounts on the same SMTP server.

  3. Open the PGP Log to see if the entries offer any clues as to what the problem might be.

  4. If SSL/TLS is enabled in your email client, you must disable it there if you want PGP Desktop to proxy your messaging. (This does not leave the connection to and from your mail server unprotected; by default PGP Desktop automatically attempts to upgrade any unprotected connection to SSL/TLS protection. The mail server must support SSL/TLS for the connection to be protected.)

  5. If either Require STARTTLS or Require SSL is selected (in the SSL/TLS settings of the Server Settings dialog box) your mail server must support SSL/TLS or PGP Desktop will not send or receive any messages.

  6. If your email account uses non-standard port numbers, make sure these are included in the settings of your messaging service.

  7. If PGP Desktop is creating multiple messaging services for one email account, use a wild card for your mail server name.

  8. Delete the PGP Messaging service that is not working correctly and send/receive email. PGP Desktop regenerates the messaging service.

If none of these items help correct the problem, try manually re-creating a PGP Messaging Service.
