====Add ip address to client_reject====

The client_reject list is one of the ways we combat spam.  If we receive spam compaints from a mail server or otherwise identitfy a mail server as a source of spam, we can add it to a client_reject list.  An email sent from a mail server on the client_reject list is rejected with a notice saying "Relaying denied due to excessive spam". To add an ip address to the list, we use admin-2.  Once the list is updated on admin-2, it is pushed out to mta-1 and mta-2.  To add an ip address on admin-2:

<pre>
Log into admin-2.nethere.net.
bash-3.00# cd /dist/files/nhmta/nethere/conf/postfix/common
bash-3.00# co -l client_reject
RCS/client_reject,v  -->  client_reject
bash-3.00# vi client_reject

-Add the ip address to the bottom of the list in the appropriate format.  It you want to reject any email from the mail server, you would use:
xxx.xxx.xxx      REJECT Relaying denied due to excessive spam
where xxx.xxx.xxx is the /24 subnet of the mail server the spam originated from.  Do not place a period after the last octet.  For example, to add a /16 subnet you would use:
xxx.xxx          REJECT Relaying denied due to excessive spam
The REJECT key word tells postfix to reject the email.  If you want to allow email from a /24 subnet, use the following format:
xxx.xxx.xxx      OK
This tells postfix to accept email from that subnet.

bash-3.00# ci -u client_reject
