Hi,
Is it possible to modify the exim.conf to auto notify the sender if their IP is blacklisted when they try to send email to server, for example it will give and email to sender to notify about their IP is blacklisted and ask them to reboot the connection if their using dynamic IP internet connection, currently i face lot of trouble because local ISP doesnt aware of any IP they have is already blacklisted by spamfilter.
Thank you.
