Sendmail

Hi guys
I am trying to get sendmail working, i can achieve this if my machine only uses /etc/Hosts. but if i try to to configure this machine to work the way all my other servers work sendmail fails to find mail server.
We normally have the system set to look at the host file first then if not found there DNS, talking to a NT PDC.
i can see the mail server using the current set up.
but sendmail just refuses to see it.
i am using HPUX 11.00.
has anyone had a similar problem in the past.
regards
andy

What does /etc/resolv.conf look like?

sendmail.cf - what is the DS variable, and the Dj variable?

Share and Enjoy! Ian

I had similar issues when I first tried to get mail off my boxes.

I had to change /etc/nsswitch.conf to DNS,files in order to make things work right.

Thats a more standardized or friendly way of dealing with the network or so our network people told me.

There are a lot of Windows based mail relay servers that have problems relaying mail from HP-UX. Push those administrators to stay current on bug fixes. I once had project delay four months becaue the relay server was rejecting mail. I spent days messing with a email attachment script while the relay server admin says nothing was wrong.

After lots of politics, he put in a general bug fix and wala, my mail went through with the original script, written 4 months ago.

I also had to set up a DNS server because our network people decided to change our internal domain name.

I don't think you need to to the nsswitch change, but if there is a dns server available, its probably a pretty good idea.

It will cause omniback 3.x problems and will totoally break openspool, if you still use it.

If you don't want to set the Dj variable in sendmail.cf you can make your hostname fully qualified.

/etc/rc.config.d/netconf

Change your hostname to hostname.yourdomain.com

Here is a good diagnostic command for sendmail, lots of nice data and it can be redirected to a file. Just run the commandline to a valid email addy, type in a one line message, then period then enter.

/usr/sbin/sendmail -v -d8.99 -d38.992 helpdesk@yourdomain.com

You shouldn't need to configure /etc/nsswitch.conf

Make sure

* /etc/rc.config.d/netconf is correct with IP, name, default gateway & subnet mask

* /etc/resolv.conf has the correct info e.g:
domain yourdomain.com
nameserver x.x.x.x

Also make sure your full domain name (hostname in the /etc/rc.config.d/netconf and the domain in /etc/resolv.conf) is configured on the nameserver as specified in /etc/resolv.conf

Then, the default sendmail should work fine.

Hi,

If you are using a Relay server you need set DS definition into /etc/mail/sendmail.cf, i.e:
DS

Where must be a resolute name.

Also you can try setting your "official domain name", i.e:
Dj

After any change in /etc/mail/sendmail.cf you must restart sendmail service, these commands allow you stop|start sendmail service:

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

You can check your pending mail queue by the comand: "mailq -v". All mails queued are in /var/spool/mqueue. Each email have 2 files, one is mail header and other is data

Remember always that sendmail variable must be set to 1, in /etc/rc.config./mailservers file.

Rgds.
