Configuring Sendmail on HP-UX 11.11 for using Exchange Server

[Lothar Krueler]

Hi,
i just want to make sendmail using MS-Exchange Server for outgoing mails to LAN and WAN.
I don't want to receive incomming mails from Exchange. I have an other HP-UX Node working that way, but it's 11.00 and its sendmail.cf seems to be copied from an older version (10.20 ?). It doesen't work on the 11.11 node.

What changes do i have to do on 11.11 node, if I use a new copy of /usr/newconfig/etc/mail/sendmail.cf file ? Are there further changes necessary ?

Thanks in advance
Lothar

Hi,

if you don't want to receive email to this host, don't start sendmail process. I fit is already done : /sbin/init.d/sendmail stop
Copy /usr/newconfig/etc/mail/sendmail.cf to /etc/mail/sendmail.cf
- configure macro DS to DSexchange_relau_name
- configure macro Dj$w. to Dj$w.domain_name.
- put to /etc/hosts server_IP hostname hostname.domain_name. (don't forget the dot at the end)
- start end stop sendmail to take modifications in sendmail.cf active.
- configure exchage to accept relay this host.

Hope this helps.

Hi,

If your DNS has MX record defined for your Exchange server, just copy the sendmail.cf file from /usr/newconfig/etc/mail to /etc/mail and restart the sendmail daemon.

In order to check if MX record is defined or not, do the following -

nslookup
>server (IP address of your DNS server)
>set type=mx
>(your domain name)

If no MX record is defined, set DS parameter to your Exchange-Server in sendmail.cf and restart your sendmail on this server.

Modify sendmail.cf file from /etc/mail

vi /etc/mail/sendmail.cf
look for DS flag by /^DS
and write your exchnage server name infront of it
DSyour exchanger server

Save and quit sendmail.cf
/sbin/init.d/sendmail stop ; /sbin/init.d/sendmail start

look for /var/adm/syslog/mail.log for more info

Hi Fabrice, Manjeet and Uday,
thanks for your helpful assistence. It didn't work at once, but i got an mail with the following message:

Warning: message still undelivered after 4 hours
Will keep trying until message is 5 days old
451 [the email-adress]... [the domain]: Name server timeout

So i used SAM for looking up "Name Service Switch" for hosts (in Networking and Communications). On the working 11.0 node i found /etc/hosts as first source, in the 11.11 node there was DNS as first, NIS as second and /etc/hosts as third source configured. I changed to /etc/hosts as first and none as second source. I didn`t reboot the machine but restarted sendmail and after a while the mailq was empty and i got the mails via Outlook.
I'll try if its necassary to run sendmail-daemon for sending only.
