I wrote a similar thing a year or two ago. Users initially authenticate
with their Unix userid/password, and are then presented with a web screen
which offers them:

.forward file management
vacation message management
opportunity to set extra email aliases for themselves
local message-list (un)subscribe
a simple(r) interface for setting Exim per-user filters
an interface for management of a per-user bogofilter
(training with their own spam and ham files and
optional retrieval of spam which has been dumped in
a per-user circulating spam bucket)

Its a messy bunch of perl cgi scripts with a few bits of C 
to do permission-sensitive things. Its extra-messy because
most of the filtering action takes place on a mail hub where there
are no user accounts, but the users mail/.forward/.vacation 
files live on a different host, so I dont know how portable    
it would be...
