Note: The following is part of a series of steps to setup an email server using Exim 4.x, with imap and webmail access. It will use winbind to get user information from an NT server. If you found this page via a search engine it may not cover what you need or you may need to start at the beginning to understand everything I have done.

Note: This page deals with an older version of Exim and just enough to run it with LRP/LEAF. It may be that this page of mine may be more helpful to you for Exim 4.x help.
