Mail queue: Possible unwanted mass-sending of emails
If a lot of emails are sent by the QUIQQER-Mailer (with queue active) at once, the queue limits may be ignored and the Mailer tries to send all emails. This should not happen and the limit has to be considered at all times.
Possible starting point: Every $Mailer->send()
call builds a new instance of QUI\Mailer\Queue
.
Needs further research and testing.
