SPF is a good starting point, have you made sure that you've added the IP ranges to your SPF record?

I have the IP for the web host server in my SPF record but according to message trace this is not the "From IP" ?
Message trace "From IP" seems to change and I have seen two class C networks so far which are not part of my web host server range.

Is it possible to set a rule based on the "Message-ID" header like "@http://www.mywebsite.com" or the "From:" header?

    Rules give you a lot of flexibility, but I would suggest fixing that SPF issue first.

      Hi VasilMichev 

      From previous Microsoft help advice I have tried adding the IPs to the default connection filter but never had any luck?
      This is what my SPF record looks like v=spf1 +a +mx +ip4:"IP of shared web host server" +include:spf.hostedmail.net.au include:spf.protection.outlook.com -all
      If I go the header rule way could I set up multiple criteria based on "Received", "From", "Message-ID" and am I correct with using "A message header includes any of these words" (or is it a pattern?)

      Thanks
