Yes, you didn't read my response. Being able to send a mail from
Google to GMX means nothing in this context.

Again: GMX *requires* that the FROM address is a GMX address. This
means that you MUST NOT send a mail FROM 'pjohnson1 at uclan.ac.uk'
via GMX' servers. The FROM address MUST be 'something at gmx.com',
the account/login name MUST be 'something at gmx.com' and the
password MUST match.

All capitalized words as per RFC-2119 ;)
