Gmail uses multiple certificate names for SMTP and IMAP SSL certificates. Gmail also requires SSL to be enabled to connect to their mail servers.  Symantec Encryption Desktop cannot proxy SSL traffic enabled within the mail client and causes problems with the connection.  


Since Gmail uses multiple SMTP/IMAP servers and several different hostnames for the SSL certificates this causes multiple proxy services to be configured in Symantec Encryption Desktop, none of which will work.


You may be presented with a smiliar error to the following if you have SSL configured on the mail client.  This means that you need to disable SSL in the Apple Mail client and then restart Mail.




This is due to the way Gmail handles the SSL certificates and having SSL enabled in the Apple Mail client instead of allowing Symantec Encryption Desktop to enable the SSL session.  This requires you to setup on service with a * in the mail server settings to enable all the SSL certificates to that Gmail uses to work and proxy the connection.
