Email to fails with Server error: '550 invalid DNS MX or A/AAAA resource record'

HP Recommended
DeskJet 3630

Dear HP experts,


When I send an email to my printer [edit] (of course changed named)) from any account at the leading German mail provider like,, or my personal domain then I get an error like:


The following recipient(s) cannot be reached:

      '' on 06.02.2020 11:43

            Server error: '550 invalid DNS MX or A/AAAA resource record'


It does work from and from my company mail address.


Thus it seems HP made a misconfiguration of the domain that's detected by the much more stricter checks in Europe. Is someone at HP able to fix this?


Thanks Peter
