I have a problem with emails not being received when sent through a form. I've contacted with hosting provider and they are not of much help.
The form was working perfectly well untill yesterday morning. If I use the email used in the form from webmail, it sends/receives emails, but when user submits his registration the 2 emails supposed to be received do not arrive.
The form has 7 steps, 1 email is sent on second step, the second at the end. None of them arrives, but hosting company tells me that they went out. So, I'm lost here. I'm sure this is a pretty simple thing, but I don't know what to do about it.
Form is in Spanish but very easy to understand, code is in english. Form is [url removed, login to view]
Emails are sent using SMTP. My programmer is on holidays and I need to solve this issue.
