I am following this solution Exim4 - temporarily freeze outgoing emails from specific user (Exim4 - temporarily freeze outgoing emails from specific user)
I am able to get email freeze from specific sender, but only when I send it from console through "telnet xxx.xxx.xxx.xxx 25". Solution is not working when I send emails from Horde/Roundcube and any Desktop Client.
Please guide me where I am doing wrong ?
