Stop or Start the Milter MTA Agent

You can configure Sendmail or Postfix to stop processing emails when the Milter MTA agent is stopped.

To stop or start the Milter MTA agent

1. Find the wgnmilter script installed with the agent in the /init.d folder.
2. Run the wgnmilter script .

   Example: On Red Hat machines the commands to stop or start the agent take this format:

   /etc/init.d/wgnmilter stop
   /etc/init.d/wgnmilter start
   

To configure Sendmail to only send emails when the Milter MTA agent is running

1. Open the Sendmail configuration file sendmail.mc.

   Find this file in the Sendmail configuration directory. This directory is normally /etc/mail.

2. Add one of the following options to the line that specifies the socket connection.

   F=R

   Specifies that Sendmail rejects emails arriving from an Exchange or Domino server.

   F=T

   Specifies that Sendmail temporarily fails emails arriving from an Exchange or Domino server.

   Position the F option inbetween the S and T options. For example:

   INPUT_MAIL_FILTER(`WgnMilter', `S=inet:9999@ux-mailsvr-w2k3.unipraxis.com,
   F=R, T=S:4m;R:10m;E:10m')dnl
