The seed migration also guards against SECRETS_KEY being unset at migrate
time (encrypting the .env password would otherwise throw and take the
whole migration down, on a fresh install as much as in the test suite),
and the four tests/Feature/Mail files written before this migration reset
the mailbox table in their beforeEach so they keep testing what they did
before mailboxes.key collided with the seeded rows.
Review of Task 4: MailboxResolver::for() only fell back on a missing
mapping or a missing row. Deactivating a mailbox — the operator's
explicit "do not use this" — left it resolvable anyway, so
MailboxTransport reached it, found isConfigured() false, and threw
instead of quietly using the next candidate the way every other
"this mailbox is unusable" case does. Worse, __toString() still
reported the deactivated address as though it were healthy.
named() now runs through a new active() filter at BOTH lookup sites —
the purpose's own mapping and the system fallback — so an inactive
system mailbox is refused exactly like a missing one, not handed out
as the last resort. A missing password stays deliberately unfiltered
here: that is a MailboxTransport concern (loud failure naming the
mailbox), not a resolver fallback trigger — silently rerouting mail
because a password hasn't been typed yet would hide the gap instead
of surfacing it.
Added two tests and mutated active() to a no-op filter to confirm they
catch it: both failed (one expected the system mailbox, got null; the
other expected null, got the inactive mailbox's full attribute dump).
Reverted, reran, both pass again.
