Hello Friends,

I m having problem with sendmail and DNS. I m trying to setup local mail server, the MX record resolve from lcoal DNS server.

here it is...

one mail server ------> DNS server ---------> second mail server "sendmail
"sendmail as MTA" as MTA"

details:
1) one mailsever:
hostname: mail.llc.com
ipaddress:192.168.0.2
MTA: sendmail
POP: on
IMAP: on
2) second mailserver:
hostname:mail.xyz.com
ipaddress:192.168.0.1
MTA:sendmail
POP: on
IMAP: on

3) DNS server:
hostname: ns.example.com
ipaddress: 192.168.0.3
MX records for mailsever in FWD zone file: MX 5 mail.llc.com, MX 5 mail.xyz.com

[root@ns root]# dig ns.example.com MX | grep "MX" [on DNS server]
; <<>> DiG 9.2.2 <<>> ns.example.com MX
;ns.example.com. IN MX
ns.example.com. 86400 IN MX 5 mail.llc.com.
[root@ns root]#

I have setup my mail server[mail.llc.com]

1) dns client entry with the following line.

in /etc/resolve.conf file

search ns.example.com
nameserver 192.168.0.3

2) i have setup mail server with sendmail as a MTA. made chancing in sendmail.mc file with following options:

define(`confDOMAIN_NAME', `ns.example.com')dnl

LOCAL_DOMAIN(`mail.llc.com')dnl

MASQUERADE_AS(`ns.example.com')dnl

dnl #DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl ---- > commented with "#" localhost

3) i have set the m4, with:

m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

4) also given REALY entry in /etc/mail/access

localhost.localdomain RELAY
#localhost RELAY
#127.0.0.1 RELAY
192.168.0.2 RELAY [mail.llc.com]

5) also made changes in /etc/hosts

127.0.0.1 server localhost.localdomain localhost
192.168.0.2 mail mail.llc.com mail

6) Also, imap,pop service is ruuning on ns.example.com PC and sendmail running as MTA.
