Where can I find a list of domains used by free e-mail hosts?
 

I would like to prevent people from registering via free e-mail accounts (ie Hotmail, Yahoo, etc). Does anyone know where I can find a list of domains used by free e-mail hosts?

its not a list but they have a tool to lookup an email address and see if it comes from a free host. im sure you could easily write little script to connect to the page and check the result (and if you cant i could do it for you if interested).

Old list I compiled

good list

AgentCash, thanks! That list will be very helpful.

NastyJack, many thanks for the tip and the offer. But I'd prefer to use a list so that I can add/remove domains at will.

Anyone else know of a list?

That is a cool list! Thanks for the link:thumbsup
