if use sendmail you can also tell the unix e-mail god who you want to have send the e-mail.

so you could send a e-mail to all your friends and tell it that

[email protected]

actually e-mailed the letter.

while some people will get themselfs into all kinds of trouble with this its ofter very usefull in a business.

once i sent out 15,000 letters to the visa card customers of a company i worked for. i had the letter appear to come [email protected] instead of my userid because i didnt want any of the people i sent the e-mail replying to me.

here is a korn shell script that will send fake e-mail using the sendmail command

korn shell script to send fake e-mail

here are two perl scripts that will send fake e-mail

perl script to send fake e-mail uses unix sendmail command

perl script to send fake e-mail uses perl module Mail

and last dont get your self in trouble sending fake e-mails. even though the you can send a letter that appears to be e-mailed by your boss, santa claus, bill clinton the actual e-mail can always be traced back to the person who sent it.

in the case where i sent out 15,000 junk e-mails above 3 or 4 of them were smart enough to figure out who i was and replied directly to me.
