Query on usage of busybox sendmail

[sujith sankar]

Hi Vladimir,

It worked when I used a file as input to sendmail.  The file contained
the following
___________________________
To: recepient at domain.com
<blank line>
my message
.
___________________________

The command that was used is
cat mail.txt | sendmail -S server -f sender at domain.com

Thanks a lot for guiding me towards it !!

Regards,
-Sujith
