I've emailed Sales, but have not gotten a response so I thought I'd ask here.

What constitutes a user as far as licensing? For instance, on my Zimbra FOSS server I host 4 domains. I have email accounts in all four for myself, plus general Info@ addresses. Plus my wife has 2 accounts. That's 10 total. So is that a 10 user license? Even though there are really only 2 people accessing it?

I ask this more because I am about to recommend Zimbra to a couple of small business customer I have and need to understand how to calculate licensing.

I know in Exchange it's only about how many concurrent logins you have.
