Disable Sendmail on FreeBSD | How-to Guide

If you are looking for a quick way to start or stop Sendmail with FreeBSD, you have come to the right place.

According to our experts, this can be easily done by switching to Sendmail’s directory and running the make command along with the corresponding command. We can do this either as the root or via sudo.

Commands to manage Sendmail on FreeBSD:

make stop
• To restart Sendmail:
  cd /etc/mail

How to disable Sendmail on FreeBSD

1. First, we have to open the Sendmail configuration file and locate the following line in the configuration file:

   #DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

   We have to uncomment this line by removing the # at the beginning and changing it to:

   DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

   This will bind Sendmail to the loopback address only, preventing external connections.
2. Next, save the file and close the file.
3. After that, restart the Sendmail service to apply the changes.

After the above steps, the Sendmail service will be disabled on our FreeBSD system.

Our experts would like to point out that this method will disable external access to Sendmail. However, local services and processes will still be able to use it for sending emails.
