Thank you very much for your answers. I was running nessus in the same machine as nessus says is relaying.
I have changed some points in my exim.config, and now nessus says nothing about relay. But when I telnet to relay-test.mail-abuse.org, the test says that my system apears to accept one relay attempt. Here you have the main configuration of my exim.conf: qualify_domain = debys # qualify_recipient = local_domains = localhost:debys local_domains_include_host = true local_domains_include_host_literals = true relay_domains = no_relay_domains_include_local_mx no_relay_match_host_or_sender host_lookup = * # headers_check_syntax rbl_domains = rbl.maps.vix.com:dul.maps.vix.com rbl_reject_recipients = false rbl_warn_header = true rbl_hosts=* host_accept_relay = 127.0.0.1/8 smtp_verify = false ****************************************************** I think these are the main points about relaying. If you want I can e-mail too the report that I obtain from mail-abuse.org Where do you thing I'm doing the mistake? Thank you very much another time. Salvador
