Code to prevent users from entering HOTMAIL or YAHOO email addresses on a form

[Marcello do Guzman]

I have several forms on my website that I use to capture information
from visitors to my website. I also provide a lot fo free information
exchange for information. I presently capture emal addresses, in
fact, these are required fields on the form, but how do I prevent
individuals from entering a HOTMAIL or YAHOO email address?
Is there a javascript that would validate the email address on a form
and display a a message like, "HOTMAIL or YAHOO email addresses not
permitted". I have encountered several websites that actually
prevent you from entering a HOTMAIL or YAHOO email address.
Any help on this would be greatly appreciated.

Sincerely,

I do not believe that you would be able to do this with FP
validation, you most likely would need some type of custom
code to do this. I would probably start by viewing the
source code on pages that validate the (email) domain.
If it were my project, I would probably attempt this through
a custom form handler based on ASP to break the email up
into variables for the user and domain names. After that I
would check to see if the domain was equal to hotmail, etc
and if so spit out a page letting them know their error.

I would avoid putting my true email address on NG posts, you
are inviting spam.
