Hi,
I would look for contact information for the postmasters at freenet.de, as we have a problem with bulk email delivery
to that provider.
Unfortunately, we have not yet received any response to the contact form on the freenet.de homepage, nor have we
received any response to the usual e-mail addresses to postmaster and hostmaster.
I had some mail exchange with postmaster at freenet.de regarding the problem (I assume it's the same issue that you
have) around June 14. After that, no further responses to my questions, so maybe the (single) postmaster is on vacation
or they don't like to be pestered with deliverability problems of people who aren't their customers.
Cheers,
Hans-Martin
