Qmail bounces multiple unknown addresses

[UnnarB]

Hi I hope this is the right place to post this thread.
I sent a mail to a address on our server (bara@toppfarar.is) but it bounced back with this:

bunch of strange addresses there namely the "career@xxxx" addresses, why are those addresses bouncing back to me? Is this normal? Is there something I can do? We have been getting some spam lately.

Have you checked forwarding and mail groups on that mailbox? It could be set to orward to all those addresses, for some reason?

No there is are no mailgroups set up on this mailbox or mail forwarding
