Onderwerp: [Exim] $home for virtual users
Hi,

in my setup i use virtual users with one userid for all, the problem i had
was that exim can not set $home for virtual users, because it only set it
while check_local_user.

So it's impossible to use something like
save .Exim/
in a filterfile, or
save $home/.Exim/

until now i used sg+readfile to modify the filter file with a regular
expression, to convert
save .Exim/
to
save /var/imap/DOMAIN/USER/.Exim/

that worked, but it's ugly, and it's not the full support like exim does,
with this patch, you can set home_directory in a router to set $home
directly, this will be carried over to the transport too, so you can
(SHOULD) use
create_file = belowhome
their too.

As usual, comments to the list, flames to me.

ciao
