"""send retries for 24 hours, and an account's sync health
|
||
|
|
|
||
|
|
A send the mail server could not take (SMTP unreachable, a temporary 4xx) is no
|
||
|
|
longer failed at once: the outbox row goes to ``retrying`` and is tried again
|
||
|
|
with growing gaps until ``retry_until`` (24 hours after the first failure).
|
||
|
|
``attempts`` counts the tries, ``next_attempt_at`` is when the next one runs.
|
||
|
|
|
||
|
|
An account whose server cannot be reached for a while carries ``sync_error``
|
||
|
|
(``unreachable``) and ``sync_error_since``; both clear on the next success.
