I’ve created a “contact me” form for my site using Foundation theme’s Form Base stack and I’ve set it all up correctly, with SMTP server (including username and password), as far as I am aware.
When using RW7 in preview mode, the form works like a charm and I recieve the form submission to the intended email address. But when I upload the files to my web hosting domain and go live, the form no longer works.
Web host often restricts mail being sent from a Web site to prevent their mail server being used for SPAM. You should look through your hosting companies knowledge base or help area. If you share the name of your host, perhaps someone on the forum has experience with them.
