How do i disable the system Sendmail on Freebsd?

If you're using FreeBSD 6.0, you can control sendmail very easily by adding variables to your /etc/rc.conf file.

Looking at the /etc/rc.d/sendmail file, it seems there are four variables used to control sendmail:

• sendmail_enable
• sendmail_submit_enable
• sendmail_outbound_enable
• sendmail_msp_queue_enable

Setting 'sendmail_enable' to 'NO' will disable all four of those options.

Thanks Fleeb for that.
