Open registration email server package?

Asking for information on email servers

[mikecupcake]

Hi everyone,

A client has asked me if it would be possible to give out webmail accounts (initally 250+) on one of their domains. They want an automated registration procedure similar to hotmail/gmail/etc but with an invite system to prevent unknown people registering.

Can anyone point me to a company offering a package solution?

thanks,
mike

I haven't used it but I did research this a while back. If you have access to your MX you can use BigMailBox to host the storage. THey take care of all the registration. Check them out for more details.
