Mail proxy connector is unable to find all the recipients for the DL list and can not proxy the message appropriately. This can occur when attempting to encrypt to a distribution list with a large number of recipients.
To resolve this issue, click the + symbol next to the name of the distribution list to expand the list which then displays all the members of the list. Expanding the list allows PGP Desktop to proxy the email message.
