Sendmail newbie


Hello all,

I have questions about sendmail, I have successly installed sendmail
on my linux machine (redhat 9). I have not done any configurations to
any files becuase I don't really know what/how to congifure the files that
are needed to be configured. I have successfully tried sending email internally to users on the box using:

[root@timedb mail]# telnet 127.0.0.1 25
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
220 localhost.localdomain ESMTP Sendmail 8.12.8/8.12.8; Wed, 3 Dec 2003 09:51:04 -0600
helo root
250 localhost.localdomain Hello timedb [127.0.0.1], pleased to meet you

You have new mail in /var/spool/mail/trantv

CHECKING RECIEVED MAIL
==========================
[root@timedb mail]# mail
Mail version 8.1 6/6/93. Type ? for help.

Subject: Mail Test!

Do not reply, This is a Test!

===========================


Finally my question is how do I send mail externally? I have tried using the same steps shown above using rcpt to: trantv826@yahoo.com and I mail gets put into the mailq with a message saying:


[root@timedb mail]# mail
Mail version 8.1 6/6/93. Type ? for help.
"/var/spool/mail/trantv": 8 messages 8 new
>N 1 root@localhost.local Tue Dec 2 14:39 14/514 "Mail Test"

N 3 root@localhost.local Tue Dec 2 15:52 14/514 "Mail Test"
N 4 root@localhost.local Wed Dec 3 08:44 14/521 "Mail Test"
N 5 root@localhost.local Wed Dec 3 08:45 14/521 "Mail Test"
N 6 root@localhost.local Wed Dec 3 09:52 12/458 "Mail Test!"
& 6
Message 6:

Date: Wed, 3 Dec 2003 09:51:04 -0600
From: root <root@localhost.localdomain>
Subject: Mail Test!

Do not reply, This is a Test!


==============================

My question is when I try to send email externally to say "me@yahoo.com". My mail then stays in the mailq and displays the message below:

[root@timedb mail]# mailq
/var/spool/mqueue (1 requests)
-----Q-ID----- --Size-- -----Q-Time----- ------------Sender/Recipient-----------
hB3F1Pgl026968 15 Wed Dec 3 09:02 root@localhost.localdomain
(Deferred: mx4.mail.yahoo.com.: Network is unreachable)
trantv826@yahoo.com
Total requests: 1

I have no clue as to what to do next......The server does not have a domain name. Do I need one before I can send mail out externally to other mail servers? I am just trying to send anywhere that accepts my mail so I can verify that it is working properly.

I would be very appreciative of any inputs that yall can suggests to me.

Sorry for the long message..tried to make it descriptive.


THANKS!

Well it says: network is unreachable. here is your problem. Try pinging mx4.mail.yahoo.com

Then I think you have a working sendmail, but a network problem.

I believe our network administrator has disabled pinging to the outside world. I can ping from within our network. So does this mean there is still a network problem?


Thanks for hope on saying I should have a working sendmail

try

telnet relais.videotron.ca 25

or

telnet smtp.mail.yahoo.com 25

Do you have an answer?

If you can ping your inside network, this is probably a gateway problem. Do you have a fixed IP? How looks your /etc/sysconfig/network ?

I tried telneting the two sites you gave me and it said:

RELAIS.VIDEOTRON.CA
===========================
telnet: relais.videdotron.ca: Name or service not known

SMTP.MAIL.YAHOO.COM
===========================
Trying 216.136.173.18...
telnet: connect to address 216.136.173.18: Network is unreachable

Yes the server is on a fixed IP.

in my etc/sysconfig/network is says:

NETWORKING=yes
HOSTNAME="servername"

you're lacking your gateway in your /etc/sysconfig/network

(you made a typo in videotron, hence the error)

just add

GATEWAY=192.168.100.1

to it, replacing 192.168.100.1 by your gateway's address

Sorry for the typo, but I still get:

telnet relais.videotron.ca 25
=======================================
Trying 24.201.245.36...
telnet: connect to address 24.201.245.36: Network is unreachable

As for lacking a gateway, what do you mean?

I should add

GATEWAY=192.168.0.01 on the bottom of my network file?


Thanks!

a gateway is the next router between your server and the internet.

get this info from your network admin. it this is a small network, it is usually the firewall.

Sorry,

The network admin is unavailable, I cannot get the gateway info by using
any commands on the command line?

No.

Go to a machine that has access to the internet.

if windows, open a command line and type

tracert www.google.com

if unix/linux type

traceroute www.google.com

you'll see the path. this should help you.

can you become root?
