If you decide a full blown MTA is too heavy weight in your environment on the different nodes (Postfix isn't the ideal choice for a so called null client), then have a look at ssmtp for example. It is provided by EPEL

http://pkgs.org/centos-6-rhel-6/epel-x86_64/ssmtp-2.61-19.el6.x86_64.rpm.htm...

If I remember correctly, this does require an outside host--that is, you have to use your ISP's mailserver as relay.

You are correct, a null client sends towards a central mailhub. That will be a properly configured MTA which does everything necessary to be compliant with current mail exchange standards.

There is another null client called msmtp

http://msmtp.sourceforge.net/

but that one isn't available being packaged for CentOS.

That compiles very easily on CentOS, however. Again, not sure if it can be used without making use of your ISP's mail server.

We are in a professional, enterprise environment I presume. Thus the self compilation approach is discouraged. Even if it is a small program which compiles easily. Unless you anyhow manage to maintain your own set of RPMs and your local yum repository.

I have an ancient page (slow site, not always up) on ssmtp, at http://www.scottro.net/qnd/qnd-ssmtp.html. It hasn't been maintained for awhile, there's a better page at the arch wiki.

When no MTA is installed, How to send an email with a cronjob?

I usually do this:

    import smtplib
    server = smtplib.SMTP('smtp.gmail.com:587')
    server.ehlo()
    server.starttls()
    server.ehlo()
    server.login('user@gmail.com', password)
    server.sendmail(from, to, message_

Hi larry,

I think your method is the easiest way.

I currently have below cronjob that sends the output to /tmp/backup.out file. it is OK.

35 13 * * * root /root/scripts/backup.sh > /tmp/backup.out 2>&1

How can I then send this /tmp/backup.out to an email address.

Here's the one I created

[root@host ~]# ls -al /root/send_email.py -rwxr-xr-x. 1 root root 382 2013-07-23 15:18 /root/send_email.py

[root@host ~]# cat /root/send_email.py #!/usr/bin/python

import smtplib from email.MIMEMultipart import MIMEMultipart from email.MIMEText import MIMEText

from_addr = 'root@host.example.com' to_addrs = ['myemail@gmail.com'] msg = open('/tmp/backup.out','r').read()

server = smtplib.SMTP('192.168.9.5', 25) server.sendmail("root@host.example.com", "myemail@gmail.com", msg) #server.sendmail(from_addr, to_addrs, msg)

Should I APPEND the PATH of the script (/root/send_email.py) to /root/scripts/backup.sh file. ?

I just ran this script (i.e - /root/send_email.py). It worked. I got the email. But no subject there. How can I add a subject called " CRON JOB OUTPUT " to the email receive .

Hope to hear from you.

IIRC, in one of your follow up post, you mention that you have the Zimbra suite installed and running on *this* machine (which is why you might have had to remove the distro's default postfix in the first place).

If above is true then you should try to figure out how to send the cron emails using Zimbra's MTA (which BTW is also postfix).

Why are you trying to re-invent the wheel?

Am I missing something here?
