Hello,

I am about to implement a webmail service for students in a school
division that has about 10000 students .... okay it is a small
school division. I am looking for something that has a variety of
requirements:

1) Will have password synchronization between the NT doamin users
and the webmail server users.

2) Has a filter for scanning for any inappropriate material like
porn, and will filter it out and send a report back to the
administrator on these instances of the content of reciever and
sender.

3) Easy to use interface that elementary students can use.

4) Would prefer it to run on linux, but Windows Server 2003 will
work.

5) We are going to be buying a new server to run this with loads of
HD space.

6) No advertising on any of the web pages.

7) The ability to disable a email account without deleting it.

8) Would like to have some customization of the look (colors) of the
webmail client, and maybe insert a logo.

I know this is a tall order, but any help would be appreciated!

Jason
