I got a response from senderbase:
Quote:Senderbase gives these IPs a neutral reputation score because we do
not have anything bad to sayu about these IPs and the volume is too
low to make a good decision on the score.
So if i understand correctly all i have to do is to send a bunch of emails so that they can rate my ips :| and frankly this does not look like a good option to me.
I'll send an email to Yahoo Tech Support and see if i can get an answer from them and if they say i have to get a good reputation i'll just start mailing stuff to friends, so who's willing to give me his email address so i can send him a pretty ecard from my server
