 | So correct me if I'm wrong, but you basically don't want to use the
 | $_SERVER['SERVER_NAME'] or $HTTP_HOST variable.  You want all users to use
 | your
 | domain when using IMP.  However you also want to be able to differentiate
 | between users from one domain to another.  So for example if you have
 | user@foo.com and user@bar.com you don't want them logging in as user because
 | their prefs will collide.  I think you want to use the vinfo hook but not in
 | the
 | traditional sense.

 | I think you can almost do this with the vinfo hook with a really small code
 | modification.  Basically you will want to enable the vinfo hook, but for
 | just
 | your domain.  So your users are going to log in as
 | 
 | user@foo.bar@kabissa.org
Amith,

Isn't the above the result what you would get just by logging in as
user@foo.bar and having realm=kabissa.org?  I don't think you need
the vinfo hook.  Of course the vinfo hook could add foo.bar to the
uid.  The issue that I can't get through my thick skull is that they 
can't login to the hosting companies courier imap server with @foo.bar. 
They can only login with their uid and password with no hint as to the
domain.  I have no idea how to do that with two domains much less 500. 
Tobias thinks that it is the uid/password combination.  That is well
above my sophistication level.  I personally am missing something here.

Tobias, am I correct in the above description.

 | This is what the user will enter.
 | 
 | The @kabissa.org will be provided by the vinfo hook.  In the vinfo hook you
 | can
 | strip off the @kabissa.org using some PHP code and use that for the user log
 | ins.  So now users such as user@foo.com and user@bar.com are differentiated
 | because internally you store their domain as part of their username.
 | 
 | Then to fix the problem with having the correct e-mail address for the user
 | you
 | need to modify the function _prefs_hook_from_addr() and use PHP to
 | manipulate
 | the username into something that you like.
 | 
 | The only Horde code that you would have to change is in login.inc.  In that
 | file
 | it displays the vdomain (@kabissa.org in your case).  Basically you need to
 | silence the printing of this and I think that should cover all your needs.
 | There might be some option to not display the vdomain, but I don't know of
 | one.
