Postfix Email Not Working In Oracle Linux

I'm new to Sendmail and I want to be able to grab various stats from the Linux servers that I manage to monitor them.

Sendmail is running on my main Linux server and I can go thru the motions of sending an email to my MS Outlook client, which is what I use at work.

However I never get the email and if I check /var/spool/mqueue, I don't see any email queued up, and if I put a tail -f on /var/log/mail, this is what I'm seeing:

Code:

Feb  3 10:20:38 computername sendmail[31432]: t13GKcri031432: from=cmmiller, size=77, class=0, nrcpts=1, msgid=<201502031620.t13GKcri031432@mailserver.com>, relay=cmmiller@localhost

Not sure what to troubleshoot here, and if anyone can point me to better information, thanks.

Hi all,

I am trying to configure sendmail on my OEL 6.5 running on VM.

I did below to set it :

1. # yum install m4 telnet mailx
2. # yum install sendmail sendmail-cf
3. # ps -ef | grep -v grep | grep -i sendmail
root 3805 1 0 05:58 ? 00:00:00 sendmail: accepting connections
smmsp 3815 1 0 05:58 ? 00:00:00 sendmail: Queue runner@01:00:00 for /var/spool/clientmqueue

4. # netstat -an | grep :25 | grep tcp
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN

5. vi /etc/mail/sendmail.mc

From:
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

To
dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

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

7. # service sendmail restart

8. # vi /etc/mail/local-host-names
oracle.com

Now if I am sending mail from 1 user (root) to other user (oracle)

$ mail -s "Test mail from root" oracle
Hello this is the test mail
.
EOT

and checking mail log under /var/mail/oracle, its passing successfully.

But when trying to send the same from root user to my company outlook account not gtting any mail.

mail -s "Test mail from root" abc.xyz@aaaa.com (trying to send to my outlook account)

Getting below error on /var/log/maillog :

May 13 10:47:47 mydb sendmail[6306]: t4DEllUD006306: from=oracle, size=244, class=0, nrcpts=1, msgid=<201505131447.t4DEllUD006306@mydb.oracle.com>, relay=root@localhost

Please suggest if something I missed out or any other problem

Hi All,

Not able to find TREE command in EL6, its working fine in EL5. Need help on this.

Below are the details.



[root@localhost ~]# mkdir -p /college/sports/performer/cricket

[root@localhost ~]# tree /college/
-bash: tree: command not found

Bare with the noob here

For some reason, when I open terminal, the prompt has changed from the usual user@localhost to user@xx-xx-xx-xx-xx-xx where the xx are numbers/letters, I am assuming hexadecimals?

Why?

The title bar of the terminal window still shows user@localhost:~ , HOSTNAME is still localhost.localdomain, so whats with the gibberish at the prompt?

I have install vsftpd and start it , but when when to try it by "ftp localhost" , but not work , would advise what is wrong ? thanks


#ps -ef |grep ftp
Code:

root     29896     1  0 10:53 ?        00:00:00 /usr/sbin/vsftpd /etc/vsftpd/vsftpd.conf
root     29899 23821  0 10:53 pts/0    00:00:00 grep ftp

# ftp localhost
Code:

Connected to localhost (127.0.0.1).

Hi, I know that it is possible to get the last background pid using the $! command, however when I use it in my QT application I got a wrong result. Below follows an example where this procedure works
Code:

[linux@localhost ~]$ (sleep 6 && echo "A test") &
[1] 3312
[linux@localhost ~]$ echo $!
3312
[linux@localhost ~]$ A test

Now my Qt application, where I got a wrong result:
Code:

./dbsync &>/dev/null &
[1] 5047
[linux@localhost comm5]$ echo $!
5047

but using the ps command it is possible to verify that the pid related to the right process is not the 5047 but 5050.
Generally it is the process that comes with the command Code:

echo $!

added of two.

I use QCoreApplication in my program. I do not know if it has something to do with this error.

Any advice is welcome

I searched the forums for my title and I am not finding exactly what I am looking for. I am not using a program to send mail, such as Thunderbird or whatever. I simply want to be able to send mail from my Ubuntu 14.04 DESKTOP version for logging. I use a program called Logwatch (used alot in RHEL or CentOS) to monitor the server itself. The program sends mail to the root user account on the machine, which I can check and see, and within the program conf file, I can add an external email address, but it never sends.

I'm familiar with the SMTP concept of sending mail, outgoing mail server authentication, etc. I don't care to run this box as an SMTP server, but I understand that I need some sort of SMTP or MTA program to send mail into the real world. I tried Postfix but couldn't get that to work, and the Logwatch program wants to use sendmail, so I installed that but I am having the same issue. I am sure it is a step I am missing.

I also can't figure out how to get the 'mail' cmd from Terminal to work. I use this command:
Code:

mail -s "test" | /usr/sbin/mail myemail@domain.com

it follows through the subject, CC, body, but when I try to hit either . or CTRL-D, it never sends the email, in fact is does nothing.

I also tried sendmail with this command:
Code:

sendmail -v my@email.com < /dev/null

I was just trying to send a test email. It logs into my SMTP mail server, which I already configured, and it tells me to type out the mail, then end with a "." by itself on a single line. I try this and it just sits there.

I am missing SOMETHING when trying to actually send the mail. I can get it written with subject and body, connected, but it never sends and I am probably missing a / or something.

I did find and follow these instructions, but it still isn't working with sendmail. If I need to go back to Postfix, I can do that, I don't honestly care what I use, I just want some programs such as Logwatch to be able to email me.

hi sir.need ur help. a desktop comp is endorsed to me with Linux system. the previous user failed to give the password for localhost root and im not able to login to the system. I really need to backup the files and programs installed and afraid to reboot since our database program is installed in the pc. would really appreciate your help.ty

I am currently running a Minimal version of Centos 6.6 Ive searched all over the internet to see if anyone has seen this problem before. I can do a iwlist scan wlan0 and see my AP but it will not connect. I have encryption turned off. Ive tried to use a static and DHCP address in the ifcfg-wlan0 file. I used a laptop to verify that I am able to connecto to my AP and get an IP address so I know the AP is functioning properly.

any help would be appreciated.

Thanks
