Hello web people, hoping you can help!
I have an weird thing happening with sending emails through the
mail() function in PHP on my server.
It's sending to fine to all addresses apart from the domain which is attached to the website I'm running on the server. (That domain uses Google Apps for their Email)
It's not a blanket Google issue, as it sends fine to gmail.com address, and even to other Google Apps domain addresses. Just that one.
I've set up the SPF record - seemingly no help!
