Hello,
I do this job in acl_check_data.
In the file deny_senders I put the domains and emailadresses I don' t want
to reach any of my users (spam).
Deny_senders ex.:
*@qq.com
*@svensinc.biz.ua
*@intersallem.eu
*@avoca37.org
*@bellis.host
*@limanaki.co.ua
*@melia.biz.ua
*@sunrise.co.ua
*@mudurnuorganik.com
*@sadsxc.akresorts.com
*@boccanervosa.com
*@instantequityhomes.com
*@creativestudio.re
*@flosmall.com.ua
acl_check_data:
deny senders = /etc/exim/deny_senders
message = Rejected: "$sender_address","$sender_address_domain"! We do not
trust your domain
Most of the spam sending adresses make a notify to proof if the adress
exists:
disposition-notification-to:Return-Receipt-To:acknowledge-to in the header.
So I stop this with the same file with a deny recipients in acl_check_rcpt
acl_check_rcpt:
deny recipients = /etc/exim/deny_senders
message = Rejected: Der Empfaenger Ist gesperrt, in unserer Blockliste!
Daniel

So, how does one set up the acl_check_rcpt section to use the exim_blacklist
that was defined to deny the incoming e-mail from the named domain?

I went back and looked again and found the following:
acl_smtp_mail = acl_check_mail
acl_smtp_rcpt = acl_check_rcpt
acl_smtp_data = acl_check_data
acl_smtp_mime = acl_check_mime
Just curious, why bother having scl_smtp_xxxx when they become
acl_check_xxxx?
Why not just use acl_smtp_rcpt? Just goes to show what little I know about
exim. I don't do anything fancy with my setup, because it is just me on my
home server.
