Hello,

Again Sendmail not forwarding to Exchange...

Should "domaintable" have anything in it?

Here are the config files, can anyone spot something that may be hosing
it?

I have a few issues:

1.  Sendmail accepts the mail but does not forward it to the Exchange
2003
2.  If I apply FEATURE(`dnsbl',`sbl.spamhaus.org',`Rejected
(http://spamhaus.org/)')dnl
Almost all mail is rejected, even from non spammers.

I'm not sure why Sendmail is not forwarding.
Is there a better solution/less inquisitive RBL than sbl.spamhaus.org?

here is my setup:

internet > linux (sendmail, spamassassin) > exchange2k > users >
exchange2k > internet

what this means is the following:

1. all incoming mail first goes through our spam filter
2. it then is forwarded to our exchange server
3. which then forwards all the mail to the users inboxes
4. all outgoing mail comes from the exchange2k server itself. it does
not pass through the filter on the way out.

are you stuck on a certain spot in the configuration in particular?
