spoofing sendmail

I am trying to "spoof" sendmail. Instead of saying that the mail is coming from root@domain.com I am trying to say it is coming from dba@domain.com. No, what we are doing is for work only. We are trying to send this to about 150 recipients. I have been trying to:
sendmail -f dba@domain.com
body
.
but I never receive the email. We are using sendmail 8.13.3
any help would be appreciated

Uh, I see whom it's from, but I don't see
whom it's to. (Or are you using some new
intuitive interface to sendmail?)

No, no new interface at all. Isn't that the correct way???

To send a message TO WHOM? Who is the
intended recipient? And where did you
specify him/her/it/them?

Hi,
The syntax is;

echo test |mailx -s "Subject Part" â r â from addressâ recipient1@domain.com.,recipient2@domain.com.

It should be possible to specify one or more
recipients using sendmail, too. (mailx has
some handy features, but its intuition is
probably not superior to that of sendmail.)

Re: spoofing sendmail

This worked for me:

# /usr/sbin/sendmail -f fido@fido.com me@myaddress.com
test
test
test
.

I received the message and the from said fido@fido.com.

Have you tried specifying a recipient yet?

I'll stop asking now.
