Sending eMail

At the site that I am currently at, I have been trying to
programmatically send an email by executing the UNIX mail command from
within a basic program and have been unable to do so. The command
seems to execute o.k., but the message never gets sent.

In the past I have been able to send info as attachments or as text
within the body of an email by executing the mail program .  I have
done this before on universe and d3.

I am currently working AIX 4.3 running universe 10.

I am not a System or Network administrator and was wondering if there
is perhaps an AIX process that needs to be running or something else
that I should check for?

Any advice? 
Thanks for you help.

Happy Holidays

I had a similar problem with a D3/AIX site. The sendmail program appeared to
be working. The program ran and no error messages were returned. Yet the
email was never received at the other end. It turned out to be a router or
firewall issue. The network administrator for the site found and fixed the
problem. It works fine now. Something for you to check.

I believe it was Steve McDaniel who said...


  Can you send mail from the unix shell?

  $ echo "hello" | mail  XXXX@XXXXX.COM 

  How about....

  $ cat<<EOF | /usr/sbin/sendmail -t
    To:  XXXX@XXXXX.COM 
    From: unix_user
    Subject: Testing sendmail

    Test of sendmail

    EOF


  If neither of those work then your email system is not configured
  properly and youd need to get your system administrator to configure it
  for you.

from
configure it

Thanks for the responses.  It has been determined that this is a
configuration/firewall issue that i hope can be resolved.

The problem I run into most when sending e-mails via sendmail is not
having the receiving isp in the hosts file.  When the message is
relayed to the smtp processer on the network, the message is rejected
because the source is not recognized.

If you're on a unix system check /usr/adm/sylog/mail.log for the
results of your efforts.  Often googling the error will point you in
the correct direction.

Another tip is to make sure that the smpt processor on recogiznes the
unix box as a "trusted user" so that it will relay your messages.
Take care,
