I recently moved a wordpress site from a staging to a live server and noticed that I am no longer receiving any emails via php for anything: comments, new users or form mail (Cforms but I've since tried others).
To the user it looks like the mail is being sent, but it isn't being received. I have tried the smtp approach and this works better (although an SMTP error is being reported by some).
Does anyone know anything about this?
I have a number of other WordPress sites and they can send emails fine. I have tried all manner of email combinations in admin and users but just can't get anything to go via php.
Is there a trend of this when a site is moved to a new domain?
I've spent ages looking into this and would really appreciate some help as I'm completely out of ideas!!!
