[thiagovulcao]

Hi guys, i'm new here. I'm from brazil and I need some help.

I have to provide external access for some accounts. Just the manager of each sector can access your account, but i don't know how i do this.
If someone can help me, i will be thankful.

Sorry about the bad english, and thanks Google Translate. =D

But all accounts should work in webmail and some accounts has access outside of internal network.

That's the problem, i don't know how to do this config.
