solaris mail query

Hi,

I have deployed the same script on a number of Solaris application servers.
It is run by cron every ten minutes to check the OS for application daemons.
If any of the daemons is found not running, a message is generated to a temporary file.
At the end of the script the there is a check to see if the temporary file
exists. If the file exists, its contents are sent via /usr/ucb/mail through an ms exchange relay server using the following code:

if [ -s /tmp/daemon_check.$$ ]
then

cat /tmp/daemon_check.$$ | /usr/ucb/mail -s "Warning $Host" ourgroup@domain.co.uk

fi

There a is noticable difference in behaviour in the code on various servers.

On a V880 running SunOS 5.8 Generic_117350-28 the code does not work; the only way I can get any mailed response is to change the line

cat /tmp/daemon_check.$$ | /usr/ucb/mail -s "Warning $Host" ourgroup@ourdomain.co.uk

to

/usr/ucb/mail -s "Warning $Host" ourgroup@ourdomain.co.uk < /tmp/daemon_check.$$

The actual output received in MS Outlook has the "To:" field set to "root@bghgapp01.ourdomain.co.uk" and the Subject as "Output from "cron" command"; the contents of the mail is:

your "cron" job on bghgapp01
/usr/local/scripts/daemon_check.ksh

produced the following output:

No bseng process for genhgat
No wfeng process for genhgat

This behaviour is the same on another V880 running SunOS 5.8 Generic_117350-29.

This contrasts with the the output on a V440 running SunOS 5.9 Generic_118558-10; the subject field on the received email is correct - "Warning blpapp01", the "To:" field is OURGROUP which is also correct. The output in the mail body is also correct:

No wfeng process for llophte

The extra, unwanted output:

your "cron" job on bghgapp01
/usr/local/scripts/daemon_check.ksh

produced the following output:

is not present

The code that generates this correct version of the email is:

cat /tmp/daemon_check.$$ | /usr/ucb/mail -s "Warning $Host" ourgroup@ourdomain.co.uk

Can this difference be explained simply by the OS version?

Thanks,

J
