[imp] Webmail

[Thomas Souza]

Hi,

I am looking for a message solution to solve my problem. I need in my office 
internal and external mail service. I already use QMAIL + Vpopmail + 
Courrier Imap + Squirrelmail but I dont like the poor Squirrelmail interface 
and I read many good things  about horde and IMP.

My questions are:

- Need I to uninstall QMAIL ???
- Does horde has a MAILSERVER too ???
- Can I connect my users with my Active Directory and manage them ?

Thanks,

Thomas Monte
