How can I get real e-mail?

I will send e-mail with user's name and password to player's e-mail. But if the player write false email adress, how can i prevent it? Can I know it, so, real e-mail?

No, you can only check if email matches to email pattern using regex.

local email = "[email protected]" 
if email:match("[A-Za-z0-9%.%%%+%-]+@[A-Za-z0-9%.%%%+%-]+%.%w%w%w?%w?") then 
    outputChatBox("VALID EMAIL") 
else 
    outputChatBox("INVALID EMAIL")                 
end 

It is enough for now, thanks

I'll try it.

Edit:

It's work. Thanks
