Description
This issue aims these paragraphs from https://symfony.com/doc/current/mailer.html#always-send-to-the-same-address :
Use the
allowed_recipientsoption to specify exceptions to the behavior defined
in therecipientsoption; allowing emails directed to these specific recipients
to maintain their original destination:
With this configuration, all emails will be sent to
youremail@example.com,
except for those sent tointernal@example.com,internal-monitoring@example.fr,
etc., which will receive emails as usual.
The wording "exceptions" and "except" is a bit misleading, to me it means that the mail is sent to allowed_recipients addresses and not recipients addresses anymore. But in fact, the mail is still sent to recipients addresses.
It's not a feature bug as the contributor intended to replicate the whitelist behaviour of swiftmailer, but it's explicitly mentioned in swiftmailer documentation that the mail is still sent to recipients:
all email addresses matching these regexes will be delivered, like normal, as well as being sent to dev@example.com
