5.3. Webmail

Webmail much more easily then other services leaves the control of the authentication to the IMAP server (that is always localhost, and that's why users need to be redirected to the apache of the box where their mailbox resides to check webmail). Consequently we don't even need to configure the LDAP support on the webmail software. The software we chose is IMP (the php mail client of the Horde framework) since in this moment it is the only one supporting some sort of integration with PGP.
