I am creating a Email Program in which i am facing aproblem for the creation of new user
it depends on which mail server you use. i personally like qmail and think everyone should use that 🙂 http://qmail.org
there is an add-on to qmail named vmailmgr: http://vmailmgr.org - there is a set of php extensions that allow you to add and remove users and aliases.
No problem at atll.Contact for further details.
