Wish list for the SOAP Interface
is_mail_in_use($email)
This method would simplify the development of bulk operation like user creation with email alias: e.g create user create alias I for the user create alias II for the user create alias III for the user -> this alias is in use - error - rollback until user creation. A is_mail_in_use method can help to prevents such ugly rollbacks.
Enumeration methods which returns a list for email_domains email_user etc.
Necessary for developing converter, etc.
