Linux / UNIX: Change Crontab Email Settings ( MAILTO )

Q. I'd like to send email to instead of default root user. How do I change email settings under crontab file?

A. A crontab file contains instructions to the cron daemon.

An active line in a crontab will be either an environment setting or a cron command. An environment setting is of the form:

 name = value

where the spaces around the equal-sign (=) are optional, and any subsequent non-leading spaces in value will be part of the value assigned to name. The value string may be placed in quotes (single or double, but matching) to preserve leading or trailing blanks. The value string is not parsed for environmental substitutions, thus lines like


will not work as you might expect.

MAILTO Variable

In addition to LOGNAME, HOME, and SHELL, cron will look at MAILTO if it has any reason to send mail as a result of running commands in "this" crontab. If MAILTO is defined (and non-empty), mail is sent to the user so named. First open your crontab file:
# vi /etc/crontab
$ crontab -e
To send email to, enter:

If MAILTO is defined but empty (MAILTO=""), no mail will be sent.

Otherwise mail is sent to the owner of the crontab.

Thanks, never even thought it could be changed, I always used my .forward for this. Very handy.

I too have always the “.forward” option. This is done by the follwing…..

create a new file called .forward
vi /root/.forward

Enter the email address on the first line in the file.

Save (w) the file and exit (q)

Now, anytime the ‘root’ user get an email, it will automatically be forwarded to the address you specified in the .forward file.

You can also place the .forward file in users home directories /home/user1/.forward

Thanks for the info up above though, I’ll have to check that out.

Hi All,

Please help me out..

I configured cron job under FTPPKR user.i’ll get mails from whenever cron runs..But whenever i need the mails to be delivered from user.

Is it possibe? If yes, please help me out..

Yes, that’s entirely possible. Just figure out if the emails are being sent with sendmail or postfix, then adjust their settings to reflect that. You could deploy address rewrites to achieve this, for example.

SOLARIS does not support the MAILTO feature. Instead one needs to append the crontab entry with | mailto user@domain
00 12 * * * | mail user@domain

Mail addressed to ‘root’ is often redirected to some other account using /etc/aliases. You might like to edit (or add) the line beginning with ‘root:’ to point to some other account.

But, How if I dont want to receive notification from crontab? How to set it ? Because I’m monitoring mail server, and notification from crontab unnecessary for me.

@alex: add >/dev/null 2>&1 to the end of your line(s) in crontab. This will redirect all crontab output to /dev/null

What command is cron using to send email? I’m trying to get cron working with esmtp, but no luck so far.

I wanted to know under what circumstances will the email be sent.
Is it only when cron encounters a warning or error
Or even when the commad is executed succesfully

I am new for cronjob so help me.
How to send a automatically mail to fix mail address .

While using cronjob when my cronjob fails then the mail is sent to the user who is login but not to mailto user. What is required to send mail to the “mailto” user even when the test fails.

I’ve setted up a new cron (rsync job), the first few days it mades errors which I get by email. Now it looks to work fine, but I don’t get an email. Someone knows why?

thanks in advance

Check your server mail log file. Also, check your spam folder.


15 Sebastian June 2, 2014 at 2:04 pm
