sendmail prob

khilari — Wed, 13 Dec 2006 10:28:34 GMT

Hi guys, I am posting the outputs of three emails that I sent out from the box which was having trouble with sendmail. Now, if u see the first 2, u see MAIL From: SIZE=20, but in the third one it doesn’t. I also did a nslookup on the domains of the first 2 and added them to the /etc/hosts (the last 2 entries)

/etc/hosts
142.238.64.147 caremgr caremgr cm
127.0.0.1 localhost loopback
142.238.64.148 das1 das #tns
142.238.64.61 cln h8193n2
142.238.64.63 med pc h8193n1
142.238.64.65 fin h8193n3
142.238.64.71 dns
139.177.222.183 mckhboc.com
209.209.51.11 mckesson.com

But the problem is that the third one that is my own domain, stjosham.on.ca. I am not getting any emails from the server. When I do a nslookup on stjosham.on.ca I get back

Care Manager 16>nslookup stjosham.on.ca
Using /etc/hosts on: caremgr

Name: stjosham.on.ca

But I don’t get any ip address to put it in the /etc/hosts file, but keep one thing in mind that it is our own domain.

The output of the emails look fine, but unfortunately they are not going through.

All three have root@caremgr.stjosham.on.ca

Do you mean why does the third not have SIZE=20?

Well, the first 2 connect to an Outbound Mail1 SMTP server and the third straight to e500mail.stjosham.on.ca

Different mail servers.

Thanks

Okay - first off - your dns resolver isn't working correctly.

What is hosts set to in /etc/nsswitch.conf?

Probably just files.

Should be

files [ NOTFOUND=continue ] dns

Next, your /etc/resolv.conf needs to contain the ip's of your dns servers.

Now, in your own domain, do you have a smart relay server? if yes, then on "Care Manager 9" server in /etc/mail/sendmail.cf set the DS macro to that smart relay server:

DSyoursmartrelayserver.itsdomain.com

well, we have a mail router. Through which all the traffic comes in and goes out. SO do u want me to put in the stjoesdc02.ad.stjosham.on.ca in the DS macro.
U see when i did a nslookup on the mailrouter i got that. 142.238.64.117 is the name server. Kindly have a look at the files outputs. And confirm if i should put stjoesdc02.ad.stjosham.on.ca in the DS macro.

Thanks

Care Manager 3>more /etc/nsswitch.conf
hosts: files [NOTFOUND=continue UNAVAIL=continue] dns [NOTFOUND=return UNAVAIL=continue TRYAGAIN=return]

Care Manager 4>cat /etc/resolv.conf
domain stjosham.on.ca
nameserver 142.238.64.117
nameserver 142.238.64.115

(mailrtr)root# nslookup
Default Name Server: stjoesdc02.ad.stjosham.on.ca
Address: 142.238.64.117

Khilari,

The DS macro should be set to identifiy the mail relay through which the traffic flows. It can be the IP of the mail relay or a host name, as long as the host name can be resolved.

Also, the "unable to qualify my own domain name using short name" messages you're getting can be corr4ected by settin the Dj$ sendmail macro to the originating server's fully qulaified domain name, or entering the fully qualified domain name in the /etc/hosts file.

Note that if you're running the sendmail daemon, you'll need to stop it and restart it after making your changes.

/sbin/init.d/sendmail stop
/sbin/init.d/sendmail start

501 Sender domain must exist - you need to set the DM macro to a really domain name. One that exists on the internet.

Hi.

If you want to disable sendmails automatic lookup of domains and leave that to your mail gateway to do that enable the use of the /etc/mail/service.switch

It should contain the following entries:

hosts files
aliases files

Just uncomment the
O ServiceSwitchFile=/etc/mail/service.switch
line in the sendmail.cf file and restart sendmail.

HTH
