it never hits the mailbox.
Let me explain further. We have a Barracuda anti-spam firewall. I can see the email was allowed, and I can redeliver it. When I check Exchange Message Tracking I see that it's being routed to the mailbox. However, as I explained before, it never ends up in the mailbox. Final disposition on this particular mail is: SMTP Store Drive: Message delivered locally to Store to firstname.lastname@example.org
Anyone encountered this? I need help finding out why this mail never hits the mailbox!
