554 Sorry, no mailbox here by that name >> service@joy-it.de

Not reachable at the email address service@joy-it.de
Can you provide a valid email to contact you?
Thank you!

Hi Flavio Gavioli,
this was my fault. The correct address is service@joy-it.net. I corrected the address in the other post. Thanks for the hint.
Best regards
Nils (Joy-IT)

Thanks a lot!!!
