Email - System Admin Inbox
Compose and send an email from the mailbox
Send a new email from the mailbox's outbound address.
Reply: pass in_reply_to=<original-message-id>. Forward: just pre-fill subject/body on the client; the message is treated as a normal new send. The sent .eml is archived in the same mailbox with direction='out' so it shows up under the Sent filter on the listing endpoint.
