The FROM: part is created by the sendmail or the mailx utility to prevent one user from pretending to be another. This is called spoofing. Spoofing the return address requires intervening with smtpd (or a pop3 server process) or rewriting mailers.
Reasonable choices:
1. put "FROM deshp" at the start of the subject line
2. have the job creating the mail setuid to deshp to change effective uid.
I do not know of mail utility that will do this without you having privilege to setuid. If you could do this, you could send emails to employees and pretend you are the CEO of the company.
