I'm getting the following (at the receiving end) – In the received message header –

Authentication-Results: hotmail.com; spf=temperror (sender IP is xxx.xxx.xxx.xxx) smtp.mailfrom=user@example.co.nz; dkim=temperror header.d=example.co.nz; x-hmca=none header.id=user@example.co.nz
X-SID-PRA: user@example.co.nz
X-AUTH-Result: NONE
X-SID-Result: NONE
X-Message-Status: n:n

and the message is going to "Junk folder".

DKIM and SPF records are setup correctly and pass the port25 verifier test (which uses SpamAssassin as the backend).

SPF record is:
example.co.nz TXT "v=spf1 mx -all"

Sending server is MX 10 (Highest priority) for the domain.

PTR and HELO hostname match. IP is not RBLed.

I have just changed the mail server's hostname. (and PTR / SSL cert etc to match new hostname).

What makes Microsoft/Hotmail so special?

Questions welcome.

A quick Google shows that this is a common occurance due to the way Hotmail is configured. Seems Hotmail/Live doesn't do live SFP look up's but rather uses a cached version.

This site explains how to fix the issue (seems simple).

Can't say I've come across it before, seems like an odd way to operate!

Thanks for that, however, "Submit a request to have your domain added to the SIDF cache" link takes me to a almost nothing page (and I am logged in). No option there to submit domain names.

Email option doesn't work either:

Delivery has failed to these recipients or groups: senderid@microsoft.com
The e-mail address you entered couldn't be found. Please check the recipient's e-mail address and try to resend the message. If the problem continues, please contact your helpdesk.

It's also giving me a slightly different message in the received headers:

Authentication-Results: hotmail.com; spf=temperror (sender IP is xxx.xxx.xxx.xxx; 
identity alignment result is pass and alignment mode is strict) 
smtp.mailfrom=user@example.co.nz; dkim=temperror (identity alignment result is 
pass and alignment mode is strict) header.d=example.co.nz; x-hmca=none 
header.id=user@example.co.nz 
X-SID-PRA: user@example.co.nz 
X-AUTH-Result: NONE

Yes, the identity alignment is the same, so what's the issue?
