Thanks,

eukhost, we have already setup everything you mentioned on Rackspace and it made no difference- so far!

The thing is this:

I haven't been looking after my current personal host for years - I've done nothing special with it - it has no SPF records or anything. But I CAN still send to Hotmail from it.

Now my Rackspace host originally didn't have much setup on it but now we DO have SPF, reverse DNS, PTR, postmaster + abuse mailboxes etc ... but Hotmail wont deliver our mails! The mail log shows that it accepts them but it doesn't deliver them to the Inbox. We've tried every variation of send method / email content possible.

SPF is NOT that critical as I know that it's possible to send to Hotmail without an SPF, as I do on my current personal host.
