The weekend is over now.

I still playing with mails !! I have notice view things :

I have several users and this machine. One is "Ocean", another is "tux", and the third one is "ren"

"ren" and "tux" can send mail to each other easily with the command from "ren" session

 echo "Hi tux"  | mail -s Subjet ren


But the user Ocean has trouble and I have read it is because of the capital O.
" User Unknow" appears (mail -v -s )

So the User Unknow error in the previous code comes from the capital O.

Now from ren session

echo "Hello free" | mail -v -s subject rlaxxx@free.fr 
rlaxxx@free.fr... Connecting to [127.0.0.1] via relay...

Perhaps it will help someone who is a real mail expert to help you fix the underlying issue. Some of them will probably be checking in tomorrow, after the weekend. We're beyond my limits.

Thank you once again.

Not I didn't not modify anything in my sendmail configuration before.

Now, as you mentionned, I modified my /etc/mail/sendmail.mc and wrote 
dnl define(`SMART_HOST', `smtp.free.fr')dnl


It seems the command make went well :

[root@rio ~]# make -C /etc/mail
make: Entering directory `/etc/mail'
make: Leaving directory `/etc/mail'


But still when I tried to send a mail :
Ocean@rio:~$ echo hello | mail -s test rlaxxx@yahoo.fr

(I have changed the outgoing adress this time )

[root@rio ~]# mailq
                /var/spool/mqueue (1 request)
-----Q-ID----- --Size-- -----Q-Time----- ------------Sender/Recipient-----------
o78Fo4HS016111        6 Sun Aug  8 17:50 <Ocean@localhost.localdomain>
                 (host map: lookup (yahoo.fr): deferred)
                                         <rlaxxx@yahoo.fr>
                Total requests: 1


the mail do not leave the queue.

I had a look at the following page :


map lookup

I don't understand everything but I can run the following command (see at the end of the page)

sendmail -v -d8.32 -qIo78Fo4HS016111

Running /var/spool/mqueue/o78Fo4HS016111 (sequence 1 of 1)

221 mta1013.mail.ukl.yahoo.com


And the mail arrives at destination. Great !
Does this help ?

Have you modified /etc/mail/sendmail.mc to define your ISP's SMTP server in the line 
dnl define(`SMART_HOST', `smtp.your.provider')dnl

and then done 
make -C /etc/mail
?

Sorry for the quantity of info. But as I don't know what is the probleme...

Yes there is a user called Ocean. It is the main user of the machine, the one running the cron.

But there is not link between Ocean and rlaxxx@free.fr. I don't know how to use aliases.

It is specified in the cron doc that cron send mail to current user or look for variable MAILTO which is set in my case to rlaxxx@free.fr
Following your question :
Quote:
host free.fr
free.fr has address 212.27.48.10
free.fr mail is handled by 10 mx1.free.fr.
free.fr mail is handled by 20 mx2.free.fr.


Suppose I want to send a mail with 
echo blabla | mail -s test rlaxxx@free.fr


What is needed to be set up ?

Thank you very much pschaff, I hope I will make it !

Lots of info now, but I still can't spot the problem. Perhaps someone better versed in mail transport issues, than I am, will.

Is there a local user called "Ocean"? There seem to be a lot of complaints about that. If so, is "Ocean" forwarded to "rlaxxx@free.fr" in /etc/aliases, and have you run "newaliases"? What does "host free.fr" return?

My network connection is working well, I can access the server with ssh and I can ping "www.centos.org" easily.

If "mail" is a mail client, if I run
mail -s test rlaxxx@free.fr
blabla
[ctrl d]

I will not receive the mail in my free.fr mailbox. It will be stuck in the queue.
If I flush the queue ( using webmin ), the mail is corectly sent

When I removed the variable MAILTO=rlaxxx@free.fr, I guess (?) cron output should be sent to the user than did the cron (Ocean).
But, when I am under the Ocean session and I type "mutt" to read my mails, there is no mails.
But If I loggin to root and read my mail (mutt), many mails are here with errors, inclusively the one send by cron ( from Ocean user)

I am posting the mails I get

Hello



I'am sorry if I make things more complicated than is. I know, using terminal, how to read mail with mutt, and I know sending mail with "mail".

It seems you are rigth, it looks like a dns problem.

Here is my /etc/hosts file 
 more /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain localhost rio
::1             localhost6.localdomain6 localhost6
192.168.0.1     rio
192.168.0.5     marrakech

This machine is called rio and have 192.168.0.1 IP adresse

Would still like to see the getinfo.sh output.

Looks like what you have is not a mail problem but a network or DNS problem. Can you do other things such as browse the internet, "ping www.centos.org", ping other local machines? Have you tried directing the mail to a local user from the cron job? Can a local user send and receive email with a mail client?

Thank you very much for your answer.

Sorry if I haven't been clear. I'd like my server to be able to send mail automatcally, when performing cron task.
Actually, cron mail output are stocked in the "queue"

]# mailq
                /var/spool/mqueue (5 requests)

I had a look to the link you've put. But unforunatly, I don't know where to start.
Given want I need (cron sending mail to MAILTO=rlaxxx@free.fr ) shall I

1- Configure SMTP parameters somewhere on my machine ?
2- Configure sendmail : using m4, using webmin ?
3 - Configure postfix ? ( by the way which MTA am I using now ?snedmail postfix ? Which one do you recommand ?)
4- Do I need to configure domaine name somewhere ?

That's enough, I am lost

Welcome to the CentOS fora. Congratulations - Apparently you have already done the recommend reading.

Unfortunately the forum attachment function is permanently broken. The best way is to just paste it in-line between code tags:
[code]
Your

here...
[/code]

It is not clear to me exactly what you are trying to do. If you want to set up a local mail server then the following Wiki article may be helpful:

http://wiki.centos.org/HowTos/postfix

See also the upstream documentation:
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Deployment_Guide/ch-email.html

Hello,

My first post here as I recently install CentOS 5.5 on my small server. I am very pleased so far.

Unfortunaltly, I have problems with my mail configuration. I don't know anything about sendmail and dns configuration so I am just looking for something easy to set up.

I use cron to perform automatic task. I set up the variable $MAILTO in cron to my regular mail.
Cron send the mail but it is stuck in the queue.
I have the same problem is I use the command
mail

in terminal.
I can acces the queue using webmin ( I have install this one week ago --> No experience with it )

it says the following error
Quote:
host map: lookup (domain.fr): deferred


If i paste this into google, there is nothing I can understand.

Thank you for you help
