Ok there is a webmail client called roundcube after it was released someone made a new client based on it called Tuxedo Mail it costs money. I though hey I know alot about php why don't I make a free version like it. I am almost done, but there is just one feature I just can't figure out how they do it. With roundcube you need a sql database. It accepts Mysql, Mysqli, postgresql, SQli. Tuxedo mail has a built in database. How did they do it. Is there something i am missing. Thanks for your help!!

Not having looked at the code, I can only guess, but they may be using the native mbox format which is essentially a flat file system used by a lot of Linux mail systems. Or they may be using something like SQLite. Or they may have code together their own proprietary solution.
