richms: If you are going thru another host then it will be coming from a server not listed in the SPF records, so it should all go to the spam as being spoofed really, as your mail server has no right sending stuff as geekzone.
Let' not get to conclusions before looking at facts, please.
1. Forum notifications comes from the same server as the domain geekzone.co.nz
2. Other geekzone emails come only from the servers hosted at the mx server for the domain geekzone.co.nz
3. Both of these possibilities are listed in the SPF text
A quick check the mail headers would tell you that, so I don't know where did you get the idea that the emails are not coming from our server.
