Configuring E-Mail on Instant Capacity Systems

Configuring Your Server to Send but Not Receive E-Mail

For security reasons, some organizations do not wish to allow incoming mail. If you want your Instant Capacity system to be capable of only sending e-mail, and not receiving e-mail, complete the following configuration procedure:

Step 1. To prevent the sendmail daemon from starting up again when your system reboots, edit the /etc/rc.config.d/mailservs file, changing the value of SENDMAIL_SERVER to 0:

vi /etc/rc.config.d/mailservs

#########################################

# Mail configuration. See sendmail(1m) #

#########################################

#

#BSD’s popular message handling system

# SENDMAIL_SERVER:

Set to 1 if this is a mail server

#

and should run the sendmail deamon.

# SENDMAIL_SERVER_NAME:

If this is not a mail server, but a

#

client being served by another

#

system, then set this variable to

#

the name of the mail server system

#

name so that site hiding can be

#

performed.

#

 

export SENDMAIL_SERVER=0 export SENDMAIL_SERVER_NAME=

Step 2. To immediately stop the server from receiving e-mail, kill the active sendmail daemon by executing the following command:

/sbin/init.d/sendmail stop
