One of my users reported today that an email he sent to a colleague using bcc in Mac Mail was not delivered.
I have checked my outgoing email logs and found the email was indeed delivered to the main and cc'd recipients but not to the bcc'd recipients.
I have now performed tests using Mac Mail, GR Web and Outlook clients. The bcc is correctly sent and delivered using Gr. Web and Outlook clients but there is no trace of the emails being sent by bcc using the Mac Mail client (sort of by design) but also they are never de3livered either (not by design).
Client in using Mac Sonoma 14.4.0 and possible latest Mac Mail client - haven't been able to confirm version number but my tests with Sonoma 14.4.1 and Mac Mail Version 16.0 (3774.500.171.1.1) exhibits exactly the same fault.
User does not send (nor do I) many bcc'd emails so cannot be sure when the issue first appeared if it has ever worked since the new EWS was introduced.
Tested on current build of Grommunio appliance (15-04) with all updates available via GUI update today.

Any ideas on how to resolve or is this actually a bug.
