One of our clients is having trouble sending to Hotmail.com (and
possibly Outlook.com etc as well). I'm confident they aren't sending
spam and they don't run mailing lists etc.
This is a typical SMTP session transcript

Hi Paul,
First, please create an SPF record because that's best practice these days and
everyone is using it
to varying degree to weight email.
If that doesn't work then I'd suggest you open a service request with Fasthosts
and get them
involved because that's pretty much what you're being told
Another host (109.228.14.111) in your /24 is on the CBL. Perhaps you are
being punished for the sins of your neighbors.

The block does look pretty bleak...

Also, you should generally consider that any mitigation Hotmail applies comes
with an implied, "Please allow 24 - 48 hours ..."
Because, unfortunately, it does.
Aloha,
Michael.
