How to manage an email address in a team?

Hey guys,

Here is my dilemma:

I have an e-mail address, say x@x.com, which I want my team and myself to be able to manage.
i.e. We need some sort of webmail interface where we can all login and manage incoming e-mail into folders, send replies, etc. all at the same time.

Usually, I would use something like SquirrelMail from my hosting provider to access and manage e-mails, but since I don't have cPanel with my current host, I need some sort of alternative.

The only example I can think of for what I really need is Hootsuite. Hootsuite is basically a website where you can manage Twitter and Facebook accounts - you can post updates to these sites directly from Hootsuite, and you can give team members access to post stuff too.

Is there anything like this for e-mail management?

Any help would be appreciated!

 

I think desknow is good,
my organization use it too manage the forum, working together on the team, and anything else.
but i think this is not free. for more information, you can googling it or bing it....
