Shell Programming and Scripting

Hi all,
I'm trying to send a mail from Unix to my company domain. It
doesn't show me any error but i dnt even receive mail in my inbox.
I'm using

Code:

mailx -s "sub" name@company_domain.com <file.txt

I have few contents in the file which should be sent as message body of the
mail NOT AS ATTACHMENT.

I have gone thru a lot of the threads & still wasn't able to understand. M
a newbie to unix. Any help be appreciated.

Check the mail box ( in unix ) using the mail command to see , if mail sending failed due to any reason.

man mailx says

Code:

Sending mail
       To send a message to one or more people, mailx can be invoked  with  argu-
       ments  which  are  the names of people to whom the mail will be sent.  The
       user is then expected to type in his message, followed by  an  ‘control-D'
       at  the beginning of a line.  The section below Replying to or originating
       mail, describes some features of mailx available to  help  when  composing
       letters.

To put a <control-d> into a file you can use an echo command, in VI do Insert and the type <control-v><control-d><esc>, in Emacs <control-q><control-d>. Oh, on the command line it is <control-v><control-d> for Bash under Gnome.

As an experiment try...

Code:

echo "" >> email.txt
echo "^D" >> email.txt

Then do the mailx command. Still getting the email as an attachment? Try the above and then a pipe.

Code:

# Above code
cat email.txt | mailx --OPTIONS

Hey, I just tried your mailx command and it worked fine so you do not need a <control-d> in the file. I bet your email is not getting out as panyam suggested. You can examine /var/log/maillog for failures also. I can send mail to myself on my machine but trying to leave my network I get an error about unauthorized relay, which I would expect. In order to get off your machine you need to configure your Mail Transfer Agent (MTA).

Here is a discussion of changing 'sendmail' to use a SMTP server that you are allowed to access.
