mailbox_unavailable

Mailbox temporarily unavailable. Answered with 503.

What it means

The mail server did not answer. Nothing about the Mailbox has changed – messages live only in the mail server, so an unanswered request reads nothing and writes nothing.

What to do

Retry after a few seconds with the same request; this is transient.
