OK - First - I want to thank Davide and the others who helped for working
out such a nice SMTP mail program.

I am interfacing XMail as a frontend server to an Exchange 2000 server
(which honestly can't even handle the load of our less than 100 users -
in the current email environment - I think you know what I mean...)
And it has performed almost flawlessly since March 1st.  It has been
the only server on two other domains - but they don't get any mail at all
really - since December of 2003.

Now I have finally gotten everything working so it can handle all three
domains and it does everything except Spam Filtering like SpamAssassin.
Everything logged is also dumped to a MySQL database.

I do allow users to filter email based on address or domain through our
Intranet server (same box) or by address by emailing the server directly.

I have added an LDAP routine to pull the current users from Active
Directory but not in real time (kind of wasteful).  And have successfully
set up Exchange to only talk to the XMail server in both directions to
further protect it.

I have one problem left before I dive into Spam filtering...

I am Spam.  8-)  In my Internet configuration, we have a block of 16 IPs
from our provider.  Base is the router. Top is network.  I understand
that.  Let's say xxx.xxx.xxx.50 used to be just for email in and out of
the Exchange box.  51 is our outbound NAT port - EVERYTHNIG goes thru that
that is not assigned else where.  56 is the XMail server for three domains
- web server for three domains - internally it also runs our Intranet.

I am running XMail on a Dual Pentium nachine with half a Gig - so she is
screaming.  But my problem is it also has two NIC ports.  One is set up
for the Internet thru the PIX firewall - 192.168.144.66 and the other has
all the M$ stuff for the internal network - 192.168.144.4.

Any guesses where XMail sends out all the outbound emails to????  Yup.
192.168.144.4 - which is then NATted through the Firewall to our
xxx.xxx.xxx.51 IP - which is NOT DNSed (forward OR reverse 8-) to an MX
record - nor should it be!  I want any desktops that are sending email to
be classed as spam!

So I searched.  My registery had -Sp 25 -SI 192.168.144.66:25.  Thought
maybe the -Sp 25 was allowing use of the 1st LAN port - took it out.  No
change.  Left it out - works fine without it.  Read that dnscache may be
holding routes in it.  Blew it away.  No change.  Disabled the LAN port -
Bingo!  mail goes out the right IP.  So anyway - I don't get it.

Any clues?  I just tryed the Network order under Networking.  (I had a
dream...)  Still goes out 192.168.144.4....  Only way it works is to
disable 192.168.144.4 - but that is my LAN address for everything else!
