I must be missing something. Having read through the spec doc on the forward
director and also I have referenced the O'Reilly Exim book and I still don't
get my .forward problem
Ok, I got my ldap configuration from AKBKHome.com. With a little effort I got
this configuration to work and I can now do successful deliveries via an ldap
lookup to a MailDir. Here is a typical user in the ldap:
dn: uid=dan,ou=People,dc=7fountains,dc=com
givenName: Dan
mail: dan
uid: dan
sn: Figlo
cn: Dan Figlo
userPassword:: N2ZvdW50YWlucw==
objectClass: inetOrgPerson
objectClass: organizationalPerson
objectClass: person
objectClass: top
objectClass: posixAccount
objectClass: CourierMailAccount
uidNumber: 1003
gidNumber: 1003
homeDirectory: /opt/mail/dan
creatorsName: cn=admin,dc=7fountains,dc=com
createTimestamp: 20030530203821Z
modifiersName: cn=admin,dc=7fountains,dc=com
modifyTimestamp: 20030530203821Z
I am using a single uid and gid for all users and these belong to the
Courier-Imap user. Deliveries work well, and all seems happy.
Now I want to forward this user to his normal email account (almost none of the
users on this system will ever take delivery here). Since he has a "home
directory" I would like to use it to host a .forward file. Yes, I know that
with some ldap magic I can put the forward into the directory, but I won't have
the flexibility of filters (this will be very important in the future).
Here is the director section from my exim.conf file:
-----------------------------------------------------------------------
######################################################################
# DIRECTORS CONFIGURATION #
# Specifies how local addresses are handled #
######################################################################
# ORDER DOES MATTER #
# A local address is passed to each in turn until it is accepted. #
######################################################################
# This looks up the user in the LDAP directory and delivers it to the
# Courier-IMAP Maildir directory for use through SquirrelMail
ldap_user:
driver = aliasfile
search_type = ldapm
query =
"ldap://localhost:389/ou=People,dc=7fountains,dc=com?mail?sub?(&(uid=$
{local_part}))"
expand
errors_to = real-admin
user = courier
group = courier
transport = local_delivery
# This allows local delivery to be forced, avoiding alias files and
# forwarding.
real_local:
prefix = real-
driver = localuser
transport = local_delivery
# This director handles aliasing using a traditional /etc/aliases file.
# If any of your aliases expand to pipes or files, you will need to set
# up a user and a group for these deliveries to run under. You can do
# this by uncommenting the "user" option below (changing the user name
# as appropriate) and adding a "group" option if necessary.
system_aliases:
driver = aliasfile
file_transport = address_file
pipe_transport = address_pipe
file = /etc/aliases
search_type = lsearch
# user = list
# Uncomment the above line if you are running smartlist
# This director handles forwarding using traditional .forward files.
# It also allows mail filtering when a forward file starts with the
# string "# Exim filter": to disable filtering, uncomment the "filter"
# option. The check_ancestor option means that if the forward file
# generates an address that is an ancestor of the current one, the
# current one gets passed on instead. This covers the case where A is
# aliased to B and B has a .forward file pointing to A.
# For standard debian setup of one group per user, it is
acceptable---normal
# even---for .forward to be group writable. If you have everyone in one
# group, you should comment out the "modemask" line. Without it, the
exim
# default of 022 will apply, which is probably what you want.
userforward:
driver = forwardfile
file_transport = address_file
pipe_transport = address_pipe
reply_transport = address_reply
no_verify
check_ancestor
check_local_user = false
file = /opt/mail/$local_part.forward
modemask = 002
filter
# This director runs procmail for users who have a .procmailrc file
procmail:
driver = localuser
transport = procmail_pipe
require_files =
${local_part}:+${home}:+${home}/.procmailrc:+/usr/bin/procmail
no_verify
# This director matches local user mailboxes.
localuser:
driver = localuser
transport = local_delivery
---------------------------------------------------------------------
When I deliver a message, it gets swept up by local_deliver and the forward
director never gets checked. I guess I don't understand how the forward
director really works. It seems strange that I would put it AFTER the other
directors. Still, I have a POP based system running exim without ldap and the
forward director works great even though it is after all the other
directors.(did I miss that paragraph in one of the books?) Anyway, here is
the output of a successful delivery to the users MailDir EVEN THOUGH HE HAD A
FORWARD FILE.
(PS... I had debug set to level 3)

------------------------------------------------------------------------------
The forward file is pretty simple right now and only contains my email address.
Still, I see no attempt to reference the file so I assume that it not a
permission problem. I also noticed from the trace that the home directory is
completely wrong, but it sill manages to deliver to the correct location???
I figure it is something simple, but BEATS ME. Any clues would be greatly
appreciated.
