Try contacting the postmaster@ -- though I wish you luck as I have never
received a human response from either hotmail or gmail.  You might also
consider having your server listed on the DNSWL.  DKIM, too, is reportedly
helpful in pushing mail through the Yahoo!, Hotmail and GMail filters.  This
is all hearsay but you might as well try it.

Perhaps both servers are foolishly penalizing your host from being from .dk?
Are you able to disclose the sending domain?  None of the domains I guessed
have SPF records that point to mail.1.gls.dk:

% dig +short TXT gls.dk mwn.dk surftown.dk sonofon.dk
"v=spf1 mx a:mail.cohaesio.net ~all"

Did the rest of this sentence get cut off?  Are there any spam-related
headers on the GMail side that might give you some clues?
