I get:
gmx.de text = "v=spf1 ip4:213.165.64.0/23 -all"
Is that supposed to be relevant to the point, which is that publication
of SPF records affect *all* parties associated with mailboxes using a
domain name (not just the registrant), and -- particularly among large
groups (tens of thousands, millions) -- one size doesn't fit all? Can
you guarantee that no person who *receives* mail at a domain under
gmx.de will ever wish to *send* mail from a convention site kiosk, an
airport courtesy lounge, a restaurant or cafe, a public access point,
etc.?
The correct SMTP Server to inject the message via is one provided by
gmx.de for the MSA function. IOW: Tell your MUA to connect to that
Server and you are using an SPF Approved/Authorized
Submission/Relaying Server. If you are not allowed to use that
Server (due to SMTP Connection Hijacking on the part of the
Connectivity Provider then you are out of luck - You should send from
your Laptop via an Ethernet/WiFi connection).
