Hi,

i have installed SPF for my domain cyberfu.dk
Yet i have send a mail to a friend
blah@blah.tld

this adress is a forward address to blah@gmx.at

therefore blah.tld is the mailserver the connect to gmx.at
the ip from blah.tld is not on my dns list and i get an error from gmx.

how can i fix this problem?

i hope you understand what i mean :)
thanks

Mit freundlichen Grüssen / kind regards
Nicolas Wimmer

You shouldn't, it's the problem of your friend, he cannot
simply forward his inbound to a SPF-recipient forging your
MAIL FROM. Works as designed.

If you're really desperate add the IP used by blah.tld to
your sender policy, something like ?a:blah.tld

Hi,

Your friend needs to get srs implemented at the forwarder's site, or
else whitelist the forwarder in gmx.at's spf check.

For more info on SRS you (or your friend) should read Shevek's paper on
http://www.libsrs2.org/docs/index.html .

Hi Frank,

yes this is a good idea..
But, when i send a mail to a user, which is not my friend..
i can't add every mailserver in my whitelist(?)

Maybe anyone can help me in German? ;-)

thanks

Your friend needs to get SRS implemented on the forwarding server, and
in the meantime he should whitelist this forwarding server on his
receiving (spf-checking) server.
