[imp] IMP customization for several customers

[Jo]

Hi,

We have several customers whose sites are hosted on the same server. We
would like to offer a webmail service to those customers, adapted to
their specific needs (languages, servers list, etc.) and with their
specific "look & feel" (logo, colors, etc.)

Has anyone any idea how to achieve this with a unique horde/imp
installation (for example, using virtual hosts pointing to different
config directories)?

Thanks,

Jo
