Smart relay host IP

From: geeta@cdfd.org.in

Hello all,

Thank you all those who replied and asked to configure me the Smart relay
host in sendmail to forward mails to virus scanner.

But when I did that , the mails bounced back saying Host unknown (Name
server: mailgateway.cdfd.org.in: host not found) .

I have included the mailgateway in /etc/hosts file.
I think I have to put in the DNS also.

We are maintaining Primary DNS at our end. but local name resolution is
through /etc/hosts file only.

I did not assign any Public IP for mailgateway.cdfd.org.in

So if i give the private IP in the DNS will it be resolved.

our named.hosts file is as follows
*******************************
; Authoritative data for Berkeley.EDU (ORIGIN assumed Berkeley.EDU)
;
@ IN SOA www.cdfd.org.in. root.www.cdfd.org.in. (
                                1986020523 ; Serial
                                10800 ; Refresh 3 hours
                                3600 ; Retry 1 hour
                                3600000 ; Expire 1000 hours
                                86400 ) ; Minimum 24 hours
                IN MX 100 www.cdfd.org.in.
                IN MX 10 cdfd.org.in.
                IN NS www.cdfd.org.in.
                IN NS cdfd.org.in.
                IN NS sunserver.cdfd.org.in.
localhost IN A 127.1
www IN A 210.212.212.3
cdfd.org.in. IN A 210.212.212.3
sunserver.cdfd.org.in. IN A 210.212.212.7
***********************************

so if i give an entry as

IN NS mailgateway.cdfd.org.in.
mailgateway.cdfd.org.in. IN A 172.16.0.10

will the mails be routed to the mailgateway(virus scanner).

Please help.

Regards

Geetha Thanu
