Can Virtusertable Entry work for Same Domain?

which line tells you about that?
What should I do to fix it?

The:

Code:

;; flags: qr aa rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0

and the fact that there is no answer line (note the ANSWER in the output of the same command from my dns).
To fix it you should contact whoever does the dns service for your domain and tell them to change the mx record to point to your server. Otherwise you're not going to get any mail from outside.
If you are responsible for the 158.234.200.20 dns server (which thinks that it's authoritative for that domain) add a mx record, so you can send/receive mail in your network using the address user@intinfra.com and not just user.
Mind that sending local mail to a single user or aliases (without the @intifra.com part) works anyway.

It says that your dns server (158.234.200.20) knows nothing about the mx record of the domain intinfra.com

It means that the dns server you're using (the one from /etc/resolv.conf) does not know the mx record of the domain in question, as it gives no answer. You can try to change it to opendns (208.67.222.222) that seems to work

Code:

dig mx intinfra.com @208.67.222.222

; <<>> DiG 9.6.1-P1 <<>> mx intinfra.com @208.67.222.222

Got your point !!
I did tried making entry into DNS Server:

Innova1@intinfra.com IN A 10.14.73.50
Innova1@intinfra.com. IN 5 MX Innova1

and it does return ANSWER.

But then too it seems virtusertable seems not to work.
Can You please mention steps by steps how it worked for you.

You understand that using for MX record a server that is known only localy, you are not going to get any mail from outside.
Anyway if you insist, add your domain in /etc/mail/local-host-names, restart sendmail and run the following to see what you get:

Code:

sendmail -bv abhi
sendmail -bv itconsultant
sendmail -bv finance@intinfra.com

Regarding my setup, it's based on a stock Slackware sendmail, but I use my own authoritative dns servers for all the hosted domains I have, so I can send/get mail everywhere in the world.

Bathory..I think You have pretty Good Mail Server Configured !!!
Can you share with me a Good Sendmail Setup you followed through examples.

bathory · 10-05-2009, 12:09 PM

As I told you I use the stock sendmail that comes with Slackware. If you want to use it, here is the .mc file to help you rebuild yours sendmail.cf. Don't forget to make a backup of your .mc .cf files.
Have you ran the commands above? What you've got?

Bathory..
I want to share something with you.Today I have been working with my colleagues regarding the virtusertable.
What we understand is Whenever I write:

File:/etc/mail/virtusertable

finance@intinfra.com abhi

Now One thing which could see is :

I have put my Machine hostname as Innova1.intinfra.com.When I add finance@intinfra.com, it searches the name abhi in our corporate Domain (ADS) Intinfra.com. We dont have any User there so it doesnt send the mail.
My Company Domain name is intinfra.com.

My /etc/resolv.conf says:

nameserver intinfra.com

Now that was the whole issue.
I had a DNS Server personally setup called groupinfra.com.
So What I did is :

Add up in DNS Server the above entry.

Now When I run:
nslookup

>set type=MX
>Innova1.intinfra.com
It returns
Innova1.intinfra.com IN A ....

So it means its resolving ..successfuly.

Now Again I tried following the same step ..and then too..No Progress.

Bathory..I think Corporate Setting is disturbing our setup.

How is the Idea of testing this through VMWARE?
What hint you can suggest for setting up this thru VMware?
Cant I provide them domain name "ultrainfra.com" and setup DNS Server and Client and configure Sendmail.

I think that wont disturb and provide us clear picture.

Some considetations:
1. virtusertable works, regardless the fact that it searches local users in AD
2. In resolv.conf you put the IP of the dns server
3.

Quote:

nslookup

>set type=MX
>Innova1.intinfra.com
It returns
Innova1.intinfra.com IN A ....

This means that you have setup a mx record for the domain Innova1.intinfra.com and not intinfra.com (they are quite different)
4. Yes, I guess you can do your tests in a virtual machine environment.

Thanks Bathory..
I may need your help with the further proceeding.

I am going to install VMware on Windows and let you know what I did till now soon.
