My website (www.angelmoronta.000webhostapp.com) contains a contact form for users to get in touch with my client. An issue that I discovered recently was the contact form was not sending an email containing the inputted information. The form was made from scratch with PHP and I made sure that it was linked and the correct email was displayed. I know that there is a daily sendmail quota, but I do not think any is going through because it remains 0% used. Any suggestions on how to fix this will be greatly appreciated considering this is due next week.
If you were using NON - SMTP and it stopped working this is likely due to abusive users on the same server as yourself, they will have caused abuse/issues and now it will be blacklisted by email providers hence no email is ever recieved.
