We are writing a specialized PHP e-mail client and would like to give administrators of this client the ability to create user accounts on hMailServer.
I tried out imap_createmailbox(...) but it just creates a directory in the user's folder structure but does not "create a mailbox for a new user" as we want.
Is there some kind of interface that hMailServer has so that I can enable our PHP e-mail client to create hMailServer accounts via code?
Yes there two interfaces to create accounts in hmailserver.
One, via database, you can choose account and password hash type (0,1,2,3) and signature and other classic informations. I don't recommend this method for synchronisation reason, hmail-server take a caching time to consider the database update.
Two, which i recommend is to use API COM, its offers all possible methods in all cummon languages. You have to enable D-COM in your windows server. The API guide
