Muchos gracias ;-)

I will try this ASAP! Could you tell me, where I can find the new 
fetchnews? Is it in CVS?

I also had a sucknews (but then in reverse) to grab the posts done on 
the Cyrus newsserver to be fed towards USENET, since my provider only 
allows me to use the POST command, and from what I recall, Cyrus uses 
IHAVE ? (Could be a little bit off here, not sure anymore).

Will I still need to use the sucknews to fetch articles from Cyrus and 
transport them to USENET, or did I misread the docs on this one ? ;-)

Gr,

Nils.
