# description
One page of a mailbox's messages, newest first. Read with an app password that grants `api`.

# properties.messages.items.properties.uid.description
Stable per-mailbox id — also the IMAP UID, so both protocols name a message the same way.

# properties.messages.items.properties.flags.description
Space-separated IMAP flags WITHOUT the leading backslash, e.g. `Seen Flagged`.

# properties.messages.items.properties.to_addr.description
The mailbox address this copy was delivered to.

# properties.nextBefore.description
Cursor for the next page — pass as `before`. Null when this is the last page.
