"Ich versuche mich zu registrieren, erhalte aber keine Verify-Mail, auch
nicht beim erneuten Senden." Traced rather than guessed, and the evidence is
in storage/logs: the address appears three times, so the mails were built and
handed to a transport that writes them to a file.
MAIL_MAILER=log. MailboxTransport::resolution() short-circuits on it —
NON_DELIVERING is ['log', 'array', null] — so every purpose mailer becomes
the log transport however well the five mailboxes are configured, which is
correct for a development machine and exactly what was happening here.
The reason it deserves a notice is that the failure is silent in every
direction an operator would look. Mail::queue() succeeds. No job fails. The
queue empties. And the console's own mailbox test reports SUCCESS, because
MailboxTester builds its own transport on purpose — a check that honoured
MAIL_MAILER=log would report success while writing to a file. So every
instrument on the page said fine.
Now the front page says it, linked to the mail page, and the mail page says
it above the mailboxes it makes decorative. All three swallowing values are
named, not only 'log': array and an unset default do the same thing, and a
notice that only knew about one would be silent in the two cases nobody
thinks to check.
Two existing tests asserted that a clean installation raises no notice, and
went red — correctly, because phpunit.xml forces MAIL_MAILER=array so a suite
cannot send mail. They pin a delivering mailer now: the warning is about the
environment, those tests are about the estate.
