It means that your ip is greylisted in their end. There are many

a new ip, and refill the form and see their feedback about it. If it
qualifies for mitigation then you'll start friendly with them, then
they'll build a new reputation on your historic. If not, you can get a
new ip and do the same steps until you get a friendly IP.
Thank you for the suggestions. I'm afraid we can't just keep on changing
IP addresses, as there is other infrastructure tied to this IP address
(vpn, external laptops etc.) - so it would involve quite a bit of
reconfiguration. Also, I doubt that it would do much good, as we've had
this IP address for 5 years - so it is clean. There is the possibility
that Hotmail doesn't like our IP address because it is a
consumer/ADSL/end-user IP - although I've removed it from the Spamhaus
PBL database. I guess Hotmail must be using an internal database. In
this case changing to another end-user IP wouldn't do much good.
Another solution is, since your volume is very low at the moment, it
should be quite easy for you to ask from your list to add your Sender to
their contact list. This will prevent your emails from going to junk
folder, and at the same time this will increase the reputation of your IP.
I will ask a number of contacts to mark our emails as safe - who knows,
maybe it will help. Thank you.
