DKIM record RSA invalid

Hello,

I've got the latest ISPconfig running and installed the unofficial DKIM patch for ISPconfig (latest version) posted on schaal it: link
The interface works good as well as the DNS record. However somehow the RSA public key is invalid and the dkim doesn't work. When I check the DKIM key on http://dkimcore.org/c/keycheck I get the following error:

Code:

This doesn't seem to be a valid RSA public key: RSA.xs:178: OpenSSL error: bad base64 decode at blib/lib/Crypt/OpenSSL/RSA.pm (autosplit into blib/lib/auto/Crypt/OpenSSL/RSA/new_public_key.al) line 91.

I guess it got something to do with my setup of the server but I couldn't fix it. Its running on ubuntu 14.04.2 64 bit. What should I do or do I need to post more info?
Thanks for reading

 

Could you at least provide your selector and the domain?
