Hi Team,
I need to block sender domains in exim4. We are getting lot of spam emails
from some particular domains. I have done some workaround to block
them(blocked their IP in MX).
Kindly let me know how to block domains, and how to stop spam emails.
deny condition = ${if forany{<, $recipients}{match{${lookup mysql
{SELECT 1 FROM blacklist \
WHERE
"${quote_mysql:${lc:${address:$reply_address}}}" regexp entry LIMIT 1
}}}{1}} {1}{0}}
message = The Receiver does not like you.
if you you have a mysql based config, that won't hurt you to much and is
easy to maintain. As it's a regex we talk about,
you can have ".*\.com\.br" as entry and block the entire brazilian spam :)
