configure DNS and senmail on AIX 5.3 2

[J1gh2]

hi Guys

I have serached this forum for sendmail issues but haven`t seen quite what applies to me.

I am using AIX 5.3 and would like to configure sendmail on the p570 lpars. I have found that DNS was not configured so I am having to configure this from scratch. I have created the /etc/resolv.conf but I am not sure what entries I need to make in the named.boot and named.ca and named.dc.

Firstly, do I need all these files configured as I just want basic connectivity to send mail from AIX to our Exchange server. Our DNS server is a Windows 2000 machine.
1) I would appreciate a brief outline of the tasks involved in configuring DNS on AIX
2) What are the files that I need to configure and the minimal config required to connect

ps -ef | grep sendmail shows
root 65906 135618 0 16 Mar - 0:14 sendmail: accepting connections

The following are our network details for the DNS server.

I would appreciate any tips and assistance.

I would advise you get a copy of webmin

http://www.webmin.com/

to configure sendmail. It's pretty straight forward you just need to add your exchange server as the relayhost.

To do this edit /etc/sendmail.cf, search for the DS entry and add DS:exchangeservername

Make sure the AIX server can resolve the name either by DNS or your local host file.

Using webmin makes more sense as the cf file is not the most readable file.

To use DNS on AIX
Edit /etc/netsvc.conf & check for

hosts = local, bind

(bind for DNS)

Edit /etc/resolv.conf

nameserver      x.x.x.x
nameserver      x.x.x.x
domain  mydom1.com
search  mydom1.com mydom2.com

(The above can be done in smitty, but I prefer editing resolv.conf myself)

As mrn mentioned,
If you want to send mail to the outside world, edit /etc/sendmail.cf and search for DS and add the SMTP relay servername here.

Do you want your AIX servers receiving mail from other hosts?
In our environment, we don't (and Security insist we don't unless we have a good reason)
If yours is the same, change the flags of sendmail.
I chose to start mine in /etc/inittab
/usr/sbin/sendmail -q30
(no -db)
This will result in sendmail not listening on port 25 on all your hosts.
