"Seller contact email address" (BT-43) should contain exactly one @-sign, which should not be framed by a whitespace or a dot but by at least two characters on each side. A dot should not be the first or last character.

Why it fails

The seller e-mail address (BT-43) is not shaped like an e-mail address.

How to fix it

It must contain exactly one @, with at least two characters before it, and no space or dot immediately either side of the @.
