Not every software does recursive lookup (I know, this is bad, bad not my failure).

I've updated the SOA now. So let me try sending mail again ... (this message) My problem is, all the lookup stuff, and used software is out of my control. I just send mail out over the official mail relay of my Internet provider. So I can't do much, when I send an SMTP MAIL TO and receive an error, complaining about unresolvable mail address. And United Internet is one of the biggest providers in Germany. Harald Download attachment "Mail_Error.png" of type "image/png" (29138 bytes)
