Hi there,

I am trying to find out how can I block or prevent visitors from entering non-corporate email address (i.e. gmail, hotmail, yahoo…) when completing the web registration form on the site?

I want to block email addresses according to their extensions?

Please help..

Thanks in advance?

Hi

You could use a regular expression for the email field to exclude those domains.

Paul. 

I am using the pluing on wordpress site. How will I use a regular expression – i am new to this.

Many Thanks!

I figured it out.

So add this to the email Input field where it reads "Regular expression for field validation":

^([\w-\.]+@(?!abc.com)(?!efg.com)(?!anyemail.com)([\w-]+\.)+[\w-]{2,4})?$

cheers!
