Formail syntax problem

[sedawk]

Hi the Group,

I have a difficulty in understanding what is wrong with this formail syntax. The script I have is like this:

FROM=`formail -xFrom:`
SUBJECT=`formail -xSubject`

echo $FROM
echo $SUBJECT

In this way, variable $FROM can be printed correctly, but $SUBJECT is empty. If I comment out the first line: FROM=`formail -xFrom:`, $SUBJECT can be printed out.

Can anyone tell me what is going on with this formail syntax?
