[AusNOG] SPF issue sending to iiNet

[Chris Legg]

Hi all

Are there any iiNet admins who can assist troubleshooting a mail 
delivery issue off-list please?

Call centre tech supports are blaming my SPF config which as far as I 
can tell is working fine (tried on multiple domains and servers), and 
the issue only occurs on 1 particular recipient mailbox.
Both sender and receiver mailboxes are otherwise perfectly functional so 
trying to work out why they don't like each other!

thanks
Chris
