You can do that with this snippet:
--snippet start--
# catch some forged mail - Andromeda 26/06/97
sender_verify
sender_verify_reject
receiver_verify
# implement some anti-spam (RBL) - Andromeda 27/02/98
rbl_domains = rbl.maps.vix.com
rbl_reject_recipients
# implement virtual domain mail relay - Andromeda 6/10/98
sender_address_relay = "partial-lsearch;/usr/exim/relay/our_relay.domains"
# implement sender blacklisting - Andromeda 11/11/98
sender_reject = "lsearch;/usr/exim/relay/blacklist"
sender_reject_recipients = "lsearch;/usr/exim/relay/blacklist"
# implement customised SMTP error rejection messages
prohibition_message = "${lookup{$prohibition_reason}lsearch\
{/usr/exim/reject.messages}{$value}}"
--snippet end--
The files in question are:
1. /usr/exim/relay/our_relay.domains - This file contains the domains that
are relayable through my host. The format:
domain1.com
*.domain.com
2. /usr/exim/relay/blacklist - This file contains domains and
senders/recipients that are ALWAYS present in spam that still comes through
RBL. The format:
recipient@???
domain.com
3. /usr/exim/reject.messages - My reject messages that I customised. This
format is available in the documentation (yes, I finally read it) under the
"prohibition_message" keyword.
Hope this helps you... This really tightens up relaying/spamming, and I've
tried testing this overnight and it seems to work VERY well.
Hope this is helpful to others.
