I have thought about using a program like to this to offer free email in lieu of someone like everyone.net and I guess the biggest thing that scares me is the amount of time spent supporting email users' questions and problems and all that... I don't want to, rather can't afford to, spend all day dealing with technical support questions from users. And of course that's the trade off with implementing your own system like this. I realize that with only a few users, it's not an issue, but what happens when there are 1,000 or 10,000. I can see all the questions now...
How do I do this?
How do I stop spam?
Why doesn't this work?
and on and on..

I know this is a new product, but does anyone using this or anything like it (ie, a standalone product not everyone.net or bigmailbox or anything like that) have any info on the amount of spent supporting users specifically on email related stuff.
