[Exim] /etc/spammers ....

Hello All,

I am using Exim version 3.36 on redhat linux 7.3. I suspect that someone is
spamming mails from my server. So I enetered his email address in the
/etc/spammers file to reject all the mails send by him. But I found the
following line commented in the exim.conf file.

#sender_host_reject = +allow_unknown:lsearch*;/etc/spammers

If I am not wrong this has to be uncommented to make it work. I am newbie to
exim and does not know much about it.

Thank you,

Tina...
