env('MAIL_HOST')/env('MAIL_PORT') returning anything, or MAIL_URL supplying
either, now counts as "supplied" and wins over the sentinel comparison — a
relay genuinely on 127.0.0.1:2525 no longer reads as unconfigured. The
sentinel stays as a fallback for when neither signal says anything (including
under config:cache, where env() goes null and this collapses to today's
behaviour).
MAIL_SCHEME=smtp is Symfony's opportunistic scheme (upgrade to STARTTLS
if offered, don't fail if not) — not a "no encryption" statement.
Mapping it to 'none' silently turned every existing MAIL_SCHEME=smtp
installation's encrypted-when-possible connection into an always-
plaintext one. Maps to 'tls' (STARTTLS required) instead: stricter than
smtp's own default, so a relay lacking STARTTLS now fails loudly rather
than leaking credentials.
An SMTP relay with a host and a from address but no username or password
- a trusted local or private-network relay - always used to be seeded as
a placeholder, because the takeover required a username to treat an
account as real, and Mailbox::isConfigured() always required a stored
password. Laravel's own SMTP mailer has supported unauthenticated relays
all along.
Add mailboxes.authenticates (default true, so every existing row keeps
its current behaviour) to tell "does not authenticate" apart from
"authenticates, but nobody has typed the password yet" - the same empty
password column used to mean both. The takeover migration now seeds the
real account off the host/address alone and marks it authenticates=false
only when neither a username nor a password resolved; isConfigured(),
MailboxTransport and MailboxTester all read it before requiring or
sending a password; the edit modal gets a checkbox for it with the
password field's hint updated to match, in both languages.
MAIL_SCHEME=smtps or an smtps:// MAIL_URL on a non-465 port used to be
downgraded to STARTTLS because mail.encryption was derived from the port
alone. Resolve the scheme first (from MAIL_SCHEME directly, or from the
URL's own scheme via the same ConfigurationUrlParser Laravel uses) and
only fall back to the port heuristic when nothing was actually stated -
which is also what keeps this machine's invalid MAIL_SCHEME=tls from
silently steering the result.
The seed migration read config('mail.mailers.smtp.host') and its three
siblings directly. An install configuring SMTP through MAIL_URL (the
other form config/mail.php supports) never sets those individual keys —
MailManager only substitutes the URL's components in at transport-build
time, inside its own protected getConfig(). Read raw, that left the
migration seeding config/mail.php's own placeholder defaults, which the
UNCONFIGURED_HOST/UNCONFIGURED_PORT guards then read as genuinely unset:
blank host, port 0, an unconfigured mailbox, for an install that was
sending mail successfully.
resolveSmtpConfig() calls the same Illuminate\Support\ConfigurationUrlParser
MailManager::getConfig() itself delegates to, so this is the same
resolution rather than a second copy of its merge order. Verified against
the real (protected) getConfig() via reflection: the URL wins for
host/port/username/password wherever it actually supplies one, and an
unset MAIL_URL leaves this a no-op.
The takeover migration seeded `address` from MAIL_USERNAME and left
`username` null unconditionally, conflating the SMTP login with the
sender address. Whenever the two differ — an API-key username, a
shared relay login — mail would go out From the login instead of the
address the system was actually configured to send from, exactly like
this installation: MAIL_USERNAME is no-reply@clupilot.com but
MAIL_FROM_ADDRESS is hello@clupilot.local.
`address` now reads config('mail.from.address'), falling back to the
SMTP login only when that reads back config/mail.php's own unset
placeholder (env('MAIL_FROM_ADDRESS', 'hello@example.com') — the same
masking problem UNCONFIGURED_HOST already guards against for
MAIL_HOST). `username` is set to the SMTP login only when it actually
differs from the resolved address, since Mailbox::smtpUsername()
already falls back to address when username is null. display_name
now reads config('mail.from.name') instead of a hardcoded literal.
The placeholder domain for the four non-configured mailboxes still
comes from the SMTP login, not from mail.from.address — the two can
name different domains, and only the login's is proven to accept mail
for a given install.

MailboxSeedMigrationTest.php had the actual .env MAIL_PASSWORD for
no-reply@clupilot.com hard-coded into a test fixture — replaced with an
obvious dummy. Grepped the whole branch (576cfca..HEAD) and the working
tree for that string and for every other real secret value in .env;
nothing else leaked.
Separately, the seed migration's SECRETS_KEY-missing warning claimed a
password "was NOT copied into the mailbox table" even when a vault row
already existed and its ciphertext WAS carried across a few lines below,
unconditionally on $canEncrypt. An operator debugging a live mail outage
would have been sent to re-enter a password that was already sitting in
the column. The warning now distinguishes the two cases and says which
one actually happened.
The vault's mail.password row is no longer deleted by this migration at
all, in either direction: deleting it unconditionally destroyed a real
password whenever MAIL_USERNAME was empty (nowhere to carry it to), and
even on a successful carry-over a later rollback had nothing left to fall
back to. Reproduced both against real MariaDB, along with a migrations-
table drift that crashed a retry on the mailboxes.key unique constraint —
fixed with Mailbox::firstOrNew() and a transaction around each direction.
down() now goes through the new Settings::forget() instead of a raw
delete, so it stops leaving the settings cache holding what it just
removed. A skipped .env password (SECRETS_KEY still unset) now prints an
operator-visible line instead of migrating clean and failing silently
later. Host/port that resolve to config/mail.php's own placeholder
defaults are treated as unset rather than as a real relay.
