Actually in sendmail command we can use -F somename@xxxxxxxxxxxxxx so the
mail will be like it is from somename@xxxxxxxxxxxxxx username (in the FROM
Field of the receivers mail client).
But how we can use the mail and sendmail together in one script, so that
sendmail command will resolve the FROM Problem, and the mail command will do
the rest part of this TASK ?
Thanks
Rudolf
