Cannot send mail in crontab

Margarida Brito — Tue, 18 Sep 2007 12:19:13 GMT

Hi,

In command line I send mail do internet addresses but when i put the same command in crontab it doesn’t work.

Can anybody tell me why?

It is HP-UX 11.23

the content of the script testemailx is:

su - username -c "/usr/bin/rm /tmp/obj_create.out; sqlplus '/as sysdba' @ /cron_scripts/obj_create.sql;"
/usr/bin/mailx -s "TestMailx " name@somewhere.com < /tmp/obj_create.out

the line in crontab:
* * * * * /tmp/testemailx > /tmp/testemailx.out 2>/tmp/testemailx.err

Well, the simple answer is that not all environmental variables are set when running through cron.
Try adding any obvious envirnmental variables to the script as well as full paths to any command you are using.

Anything in /tmp/testemailx.err?
You seem to have absolute paths for everything except sqlplus.

Do you have read permission on /tmp/obj_create.out, created by a different user?

environmental variables:
I make in the script env > /tmp/testeMailxEnv and the result is the same as my user env, except for the following variables:
MANPATH, COLUMNS, EDITOR, HISTFILE, ERASE, PS1, TERM, LINES
I don't think this will be important...

for the output of /tmp/testemailx.err is
ttytype: couldn't open /dev/tty for reading
stty: : Not a typewriter
Not a terminal
stty: : Not a typewriter
stty: : Not a typewriter

Yes I have permissions for /tmp/obj_create.out

I also tried with sendmail comand in the script but the result was the same, no mail was send.

It doesn't seem like it.

You need to clean up your .profile and /etc/profile to not execute stty and ttytype if you are not interactive. You can guard it by either:
if [ "${-%%*i*}" != "$-" ]; then
if tty -s; then

>I also tried with sendmail comand in the script

If you can echo something after sendmail, then it would show the issue with the mail system and not cron.

the output from sendmail is one:

ok it is now working.
The output of sendemail helped.

I edit the /etc/mail/sendmail.cf

where is was
# class E: names that should be exposed as from this host, even if we masquerade
CE root
I change to
CE

where it was
# class L: names that should be delivered locally, even if DH is set
CL root
I change to
CL

Thanks for the input.
