<recipient_email>
A problem occurred while delivering your message to this email address. Try sending your message again.
 

<client>.kpnxchange.com gave this error:

Hi @jvdagaang, I see @wjb has pointed you in the right direction :relaxed: Has the Abuse team been able to fix this?


I haven’t heard from you again, so I’m assuming don’t need any more assistance. If you have any other question, please let me know!
