In-Reply-To: Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-isp@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Are you using sendmail? Apparently there's some documentation at http://www.sendmail.org/ Complaining to his postmaster is also a good idea, also complain to abuse as well if they've got it set up. Be polite :-) and they'll probably/maybe help you, otherwise have a look at http://www.vix.com/spam/ http://www.panix.com/e-spam.html http://kryten.eng.monash.edu.au/gspam.html I think there's even somewhere you can report unhelpful isp's to (like a blacklist) hope this helps Andrew Perry andrew@shoal.net.au > > Is there any way to stop relay spam mails?
