setup with two domains (Polylang)

Hi there,

I setup Polylang to direct requests from
– firefox-tipps.de to the German site and
– firefox-tips.com to the English site.

Currently my WP-address is firefox-tipps.de so K-news creates e.g. for the confirmation email link urls similar to:
http://firefox-tipps.de/de/?knews=confirmUser&…
http://firefox-tipps.de/en/?knews=confirmUser&…
which all end up 404-ing as these are not reflecting my setup.

Is it actually possible to adjust the installation somehow to cater for two different domains instead of virtual language folders?

Thanks,
Albert
