sendmail not working


Hi All,

I modified /etc/mail/sendmail.mc to include the following changes:

Modified the line to include ADCB's SMTP Address
define(`SMART_HOST', `ad.abcdsim.local')dnl

Commented the below line in the file /etc/mail/sendmail.mc
dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

Then executed the below steps:

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

But when i run /bin/mail or /usr/sbin/sendmail commands, i receive the following error in the /var/log/maillog as

Jul 26 18:40:58 adcb0293 sendmail[5626]: n6QEew0E005626: from=root, size=48, class=0, nrcpts=1, msgid=<200907261440.n6QEew0E005626@abcd0493@abcdsim.local>, relay=netcool@localhost
Jul 26 18:40:58 abcd0493 sendmail[5626]: n6QEew0E005626: to=netcool@localhost, ctladdr=root,(0/0), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30048, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1]

I am able to perform the below commands successfully:

1) telnet localhost 25
2) telnet 127.0.0.1 25

Not sure if any problems with sendmail.mc, but when i tried to send email after executing telnet localhost 25 and from this session i am able to send email. Like

telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain. (127.0.0.1).

And in the /var/log/maillog, i can see the entries like

Any my /etc/hosts looks like

# Do not remove the following line, or various programs
# that requires network functionality will fail.

127.0.0.1 localhost.localdomain localhost
10.200.4.155 abcd0493 abcd0493.abcdsim.local

I am unable to figure out where the mistake is. Please help me on this issues.

Best Regards,
Krisna

You don't need to comment it out. Just remove the Addr part, so sendmail listens on all available interfaces:
Code:
DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl
