Hello,
I need help writing code that will reject banned email domains when they are entered in a simple php form.
Serveral malicious users are entering thousands of bogus hotmail.com and aol.com addresses in a form resulting in hotmail.com and aol.com blocking my server.
I have a mysql table set up which lists banned email addresses, and this works well, but recently there have been simply to many addresses to effectly ban, and it doesn't help with the new addresses that are entered daily.
How do I write code that will check for the domain name entered into the form instead of checking for a banned email address listed in a MysQL table.
Or how do I compare the domain name of the email address listed in the form with a list of banned domain names in a MySql table?
Any help would be most appreciated.
