Can you comment on some necessary setup decisions when you are reselling DNN hosting? That implies I'm getting the acual hosting service elsewhere and reselling it.  What would you do about providing email accounts and an email control panel for each portal? True, I can set up their email accounts myself through my control panel, but they want and deserve to have a control panel of their own to administer their email accounts.

I am also having a hard time coming up with the best way to host multiple clients with DNN. Ideally for me, I'd put a fair number of similar clients on the same DNN installation. That way I only administer one DNN install. However, when a fair number of clients need to have a store, it mght be necessary to have each client in their own DNN install so they can recieve their own static IP and security certificate. Do you have any comments?

Thank you!

It is better to use separate databases for your customers. This way you save your time and avoid lots of problems during DNN upgrades, backups and restore.

I recommend to rent a VPS with a pre-installed reseller control panel and mail server software along with webmail. In this case your customers can create and manage their email accounts themselves, view their site statistics etc. And with your VPS you have Administrator access to your virtual server. This way you are independent.

I do this myself for ages and I know what I'm talking about.

If you go this way, look at Dotnetpark.com hosting first. Their VPS (they call it VDS) has all you need for DotNetNuke hosting pre-installed: Dotnetpanel panel (made as DNN module), mail server software with a nice webmail interface etc.

Thank you all three of you. This is all good advice. It is a shame to ignore all the multiportal abilities of DNN, but the reasons you mention are very real.
