Qmail sending wrong failure notices

[verdehosting]

Hello, this is a bit strange,

userA sends a email, userB gets it.

User A gets a failure notice saying that the message could not be delivered to userA, userB, userC, userd, userE, ect

the only recipient was userB, where is qmail getting all these other failed addresses, and why is it claiming that the mail failed?

this does not happen to all users, just some. deleting and recreating th euser does not stop the behaviour, reinstalling qmail-psa and recreating the queues does not stop it.

here is a snippet
