Hi
This could be a silly question but I want to be sure.

I have one site up and running on my minimus package. No problems.
I am about to add a second domain/site to my account. I have a limit of 30 so I might as well use some of them.
Looking at my resource usage, I see that "Mail hosting (qmail with clustering support)" has a limit of 1.
Does this mean that I can only have email for one of my domains? I doubt it as 30 domains and 1 email doesn't make sense, but I wanted to be sure.

Thanks
