Id like to offer email only hosting, and am looking for a system like WHMap, ClientExec, etc to handle it.
One which would allow me to create packages (disk space, number of email accounts, etc), handle users and billing, register customer domains, etc
So, a user can choose a package, register/use their own domain or use ours (eg. email.com).
Basically this would be email only hosting. So they wouldn't have a control panel, such as cPanel. They would have a panel to control their email, allowing them to create email accounts, see their disk usage, etc.
And then from our site, they can login to their email accounts.
I found SocketMail, but have to admit that Im slightly confused if this would work or not.
