 Because the sender was spoofed as coming from alu.org, the "you are on

 code 450 (= temporary failure?) for unknown users.

That's a little unusual, but does happen sometimes.

                                                    It looks like
 mailman keeps trying to resend a 450 bounce, every 15(?) minutes.

It's not Mailman trying to resend the message. It's your MTA, to which Mailman handed over the message.


 Bounces from other mail servers tend to carry the 550 code (=
 permanent failure?) and mailman gives up.

Again, it's not Mailman giving up. It's your MTA.

 Uhm, will it keep on doing this forever? It's tried sending to
 beverley over 130 times since yesterday morning.

Your MTA will continue to try to re-send that message for the period of time that it is configured to do so. With the information you have available to you, you should be able to figure out which of the messages in the mail queue of your MTA is the one you want to delete, and then you can use the tools appropriate to your MTA to delete it.



However, the MTA-specific aspects of this process are something you should pursue on a mailing list or newsgroup that is appropriate to your MTA (e.g., postfix-users), and not here.
