empty MAILTO considered as bad minute

[bjacquin]

Hi,

If I create a file in /etc/cron.d with the following content:

MAILTO=

0 *   * * *   nobody /opt/scripts/...

MAILTO is left empty here on purpose in order to disable any email to be send as per documentation:

$ man 5 crontab
..
DESCRIPTION..
       If MAILTO is defined (and non-empty), mail
       is sent to the specified address.   If  MAILTO  is  defined  but  empty
       (MAILTO=""),  no mail is sent.  Otherwise, mail is sent to the owner of
       the crontab.

Then, the following error is throw:

2017-12-18T22:28:06+01:00 cron.info ks397423 crond[11745]: (CRON) STARTUP (1.5.0)
2017-12-18T22:28:06+01:00 cron.info ks397423 crond[11745]: (CRON) INFO (RANDOM_DELAY will be scaled with factor 20% if used.)
2017-12-18T22:28:06+01:00 cron.info ks397423 crond[11745]: (CRON) bad minute (/etc/cron.d/www)

Thanks!

You can see in the cited manual page that the empty variable is created by using "" i.e. the line should be MAILTO="" and not MAILTO=
