How to Design and Code an Email System like Gmail or Hotmail?
Hello,





You will need to start at the basics: Linux.





http://www.linux.org/





These large email systems are most likely all built on Linux. I know that Yahoo uses Qmail and I believe Gmail does also.





You will need to learn as much as possible about Qmail, Sendmail, Exim, Postfix and determine which mail server system you would like to use.





The information that can be found on the internet is limitless, but these links should get you started:





http://qmail.org


http://postfix.org


http://exim.org


http://sendmail.org





Good Luck!
