'Ask for Tokens' triggers multiple mails onto moderating list

[PhictionalOne]

Pretty much the issue. at max 8 same mails. Should not happen thought.

Maybe investigate email sources.

In https://github.com/fsi-tue/ppi/blob/main/core/system_classes/UserSystem.php the function askTokens($message) is defined that is run on this action. Within this, $this->email->send() is called, but only once. In that, PHP mail() is called (also only once). There are no error messages in the DB indicating that mail sending failed at some point since April. So I assume, the issue lies in mail sending on this server in conjunction with PHP. No idea what to do about this then. Mail sending on the server seems buggy as we had issue #16, which also was suspected due to mail sending behaving strangely.
