Sendmail to send all Internet mail to internal Microsoft Exchange server

Sendmail to send all Internet mail to internal Microsoft Exchange server

Post by C C » Sat, 17 Feb 2001 02:47:59



Hello!  I have posted this in the comp.mail.sendmail newsgroup but no one
has replied from there.  Maybe someone can point me to the right direction
here in this newsgroup.  Thanks.

We just acquired an IBM RS6000 a couple months ago.  We have a Microsoft
Exchange Server in our LAN which does our mail delivery both internal and
Internet.  The RS6000 is connected to our LAN.  We would like sendmail to
forward mail that is formatted with the Internet addressing (in our case

MS Exchange server at port 25.  I have tried the following:  setup entries
of our Exchange server, and our proxy server in the /etc/hosts file.
Changed the default gateway in the Unix box to point to our proxy server,
which forwards any incoming mail to the exchange server.  When I send e-mail
to my Exchange mailbox from the Unix, the message is returned to me with the
error "There is a Host Name Lookup Failure".  We are not using DNS on the
Unix box because it is a standalone box except for e-mail and ftp to/from
internal workstations.

Thanks in advance for your help.

Carlos

In netsvc.conf put
hosts=local4,bind4
or export NSORDER=local,bind for the user who is sending the mails.

Sendmail to send all Internet mail to internal Microsoft Exchange server

Make sendmail relay all of its stuff off of the remote,
check the /etc/sendmail.cf file and find the line:

DS...

Thats the smart-relay, set it to DSyourmailserverhere

Hoof sendmail and restart it...

stopsrc -s sendmail
startsrc -s sendmail

As mentioned by others, setup your dns

/etc/resolv.conf
nameserver yournameserveriphere

/etc/netsvc.conf
hosts = hosts, bind

I have tried this but it's still the same!  I can not send out an e-mail to
a user in the Exchange machine.

Sendmail to send all Internet mail to internal Microsoft Exchange server

from /etc/sendmail.cf :

# "Smart" relay host (may be null)
# Relay host to forward outgoing mail not in the local domain to.
# To forward ALL mail to this relay host, uncomment the appropriate
# rule in ruleset 0, as indicated by the ruleset's comments.
#DSmailer:relayhostname

change the last line then refresh sendmail.

You need to have DNS setup correctly, ie setup for sendmail. Create a file named
'/etc/netsvc.conf' with the line 'hosts = local, bind'. Create a file
'/etc/resolv.conf' with the followng lines;

domain aaa.bbb.ccc
nameserver 0.0.0.0
nameserver 1.1.1.1

Insert the correct details for your companys domain and primary / secondry DNS
servers.

To check that address can be resolved type 'nslookup mail.company.com' replacing
'mail.company.com' with the correct info.

Hope this helps.
