Tabor:

Not having written directors, I'm including that par of my config file
and the comments from spec.txt and hoping you could help me out here
with the modifications so I don't break the system for the 70+ paying
users on it....

# Local addresses are those with a domain that matches some item in
the
# "local_domains" setting above, or those which are passed back from
the
# routers because of a "self=local" setting (not used in this
configuration).

# 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.
Alternatively, you
# can specify "user" on the transports that are used. Note that those
# listed below are the same as are used for .forward files; you might
want
# to set up different ones for pipe and file deliveries from aliases.

virtual_aliases:
driver = aliasfile
file = /usr/local/exim/etc/virtual-aliases.db
search_type = dbm*@
include_domain = true
file_transport = address_file

# This director handles forwarding using traditional .forward files.
# If you want it also to allow mail filtering when a forward file
# starts with the string "# Exim filter", uncomment the "filter"
option.

# The no_verify setting means that this director will be skipped when
# verifying addresses if sender_verify or receiver_verify is set
(though
# they are not set by default). Similarly, no_expn means that this
director
# will be skipped if smtp_expn_hosts is set to allow any hosts to use
the
# EXPN command.

# 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.

# The three transports specified at the end are those that are used
# when
# forwarding generates a direct delivery to a file, or to a pipe, or
# sets
# up an auto-reply, respectively.

driver = forwardfile
file = .forward
no_verify

# filter

installed.

# This director matches local user mailboxes.
