BR-DE-28
Validation message
Explanation
The email address of the seller's contact point doesn't look valid: XRechnung expects exactly one @ with at least two characters on either side, no dot right next to the @ and no dot at the start or end. If there is no address at all, this appears together with the notice about the missing email address, and a valid address fixes both.
How to fix
Ask the seller for a corrected invoice with a valid email address for its contact point.
