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.
