[NTLUG:Discuss] Sendmail Problem?

[Bobby Sanders]

I've just started sendmail on a new computer named "joe." Mail sent to
certain sites, mostly universities, is bounced with the notation:

(reason: 504 <usr at joe>: Sender address rejected: need fully-qualified
address)

Can I get sendmail to remote machines that I am really
usr1 at isp_name.com?  If so, how?

Even if this would work, is there a better solution?
