If you’d like to send me your project file I can look at it when I am in the office next, but that is likely to be Monday. I would suggest contacting your host if you’re in a hurry though and they can have a look at it for you.
Ok I will try to create some mail scripts in PHP and try them. When they also create an error - I know that there is an issue with the server - then I will contact my host. I’ll let you know when I have an answer for this.
I would contact them now with the problem you’re having, but that is just me. If I am able to get into the office today I will have a look. But I will need you to send me your project file to do so.
