how to save draft in mail system?

i am doing a mail system,
when i wrote a mail,how can i save this mail as a draft?
Is it sending a mail to myown mailbox and then save it as a draft?

And when i am sending a mail,how can i save this mail at zhe
same time?

Sorry , my English is very poor. anybody can help me ?

thanks a lot!

If I understand well, you need a mail server e.g for windows, (argosoft) is a good choice.

The e-mail is sent through your mail server and stored in the recipients server.

If you want to save drafts of your sent emails you need to check if your mail server offers this option or you can save drafts in a MySQL database.

Hope this helps.

thank you ~~

But I think commonly it is not save in zhe database.
I believe it should save in the mail server

i want to know how can i do this
