how is it possible for me to provide email address from my site to the visiting registered users like (yahoo and other email sites). now i don&#039t think it is a problem to send mail between to users registered within the site since i could do with some database ..i guess... my problem is how to get the mail addresses provided by my site to be a valid one....that is my users shoul be able to send email address to this address from other sites can i do this with asp?
