Hi,

I'm trying to get my setup working (wow) which will be the following:

___
Incoming email -> exim
            = get spam-scanned by exiscan-acl's/spamassassin
            = get virus-scanned by clamd
            = maybe do some more mailfiltering
              = relay to internal mailserver which holds the
users mailboxes
___


my bad, internal mailserver is M$-exchange 2000. I'm not an experienced
exim-user, but it works pretty well for my @home-setup and I have a
personal preference
to stay with exim, so I wont to get this done. My current problem is the
recipient-verification.
I had a look at
http://exim.planetmirror.com/exim-html-4.30/doc/html/C043.txt which
looks good,
but copy-pasting isn't enough of course. For a productive environment it
is also important (IMHO)
to understand what my stuff is doing. What I'm not understanding is the
whole LDAP-stuff. Where
can I get the informations I should replace the following:

[snip]
exchangemaillookup:
driver = redirect
data = ${lookup ldap
{ldap:///?mail?sub?(mail=${quote_ldap:$local_part}@${quote_ldap:$domain}
)}}
domains = dbm;/etc/exim/db/localdomains.db
verify_recipient
self = pass
pass_router = exchangeroute
no_more
[snip]
(?mail?sub? ??)

I don't keep my localdomains in a dbm-file but use +local_domains which
should be ok, I guess.
Another thing I don't understand is, why are those exchange-routers
after dnslookup,system_aliases
and localuser. If I get it right, I don't wont those routers but only
the router which does
"User is in exchange-db (lookup ok), go on and send it to him or else
bounce the mail".

I tried those routers and resulted in the following


Connected to mail02.domain.tld.
Escape character is '^]'.
220 mail02.domain.tld ESMTP Exim 4.21 Mon, 05 Apr 2004 16:11:08 +0200

I started exim in debug mode, here is some output

I guess, I have the wrong syntax for ldap-access but I seriously don't
know where to look for informations
that belong in there or where to find some docs which could get me the
informations (without starting studying
LDAP, in fact I don't care about LDAP, it just got in my way...) I need
to get this working. user@??? exists
on the exchange server fyi. Is there a way to test a ldap connection
with a straight-forward-client or something.


thx for any advice
