I was going to send this to Kerio support, but figured I'd ask other KMS admins for their experience and opinions first.

If I send an e-mail to person x with a bcc to person y, both x and y get a Received: header that contains only person x. Likewise, there's a To: header for only person x. Person y is not show in any header (we hide the x-envelope header for local messages).

Now, when I send an e-mail to group z (which contains all our users) with z being in the bcc field, I see this in the header:

Return-Path: <hipdude<.a.t.>>
Received: from 216.127.###.### ([216.127.###.###])
for groupz<.a.t.>;

My understanding on this subject is that none of the BCC recipients, be they individual accounts, or groups should appear in the delivered headers. Am I wrong? Do others see this same behavior?

If it matters, all the accounts used for this test are linked to Apple Open Directory, not Kerio local accounts. This issue came to light when I sent a message to our 'group z' (using only the BCC field). One of the users has her local domain mail forwarded to her external I-MAIL account, on which she had an out-of-office message. Her auto-reply went to everyone in 'group z' and displayed 'group z' in the primary headers. Of course, if anyone wants to help me blame this on I-MAIL, I won't mind! :-)

Thanks for any feedback you can provide.
