[LIH] Mail server problems

[Differentiated Software Solutions Pvt. Ltd.]

Hi,

I'm trying to setup our Linux machines to send, receive and distribute mails
over a VSNL dial-up... with very limted success.
I've tried to do the following.
1. Setup our DNS, by having a forward and reverse lookup.
    If I do nslookup with the ip address it gives the MX record
    If I do nslookup with domain name it says unresolvable. But if I do
nslookup with mail.+ADw-domain name+AD4- it gives it address.
2. I have a netscape communicator with pop server pointing to this linux
box.
    If I send mails from the Linux box using mail utilitiy I can receive the
mail.
3. I have setup the smtp to point to mail.+ADw-domain name+AD4-.
    Now when I send a mail, I get a message in netscape which is 192.168.+ACo-.+ACo-
RELAY error. Please check your mail address. My from mail address is +ADw-my
name+AD4AQAA8-domain name+AD4-
    I checked /var/log/maillog.
    the message looks as follows.
Mar 14 19:14:47 diffs-india sendmail+AFs-16540+AF0-: NOQUEUE: 
ruleset+AD0-check+AF8-relay,

nagma.diffs-india.com, arg2+AD0-192.168.1.3, relay+AD0-nagma.diffs-india.com
+AFs-192.168.1.
