freebsd : 10 : sendmail_enable="NO" : no effect?

[Mayuresh Kathe]

hello,

i am very new to freebsd and hence to this list.

have an x86-64 machine running freebsd 10 since last night.

it's a personal workstation and hence don't need sendmail.
added in the following line to /etc/rc.conf;
sendmail_enable="NO"

sendmail still starts up on boot, have to manually stop it
via "service sendmail stop" which gives the following;
Stopping sendmail.
Waiting for PIDS: 683.
sendmail_submit not running? (check /var/run/sendmail.pid).
Stopping sendmail_msp_queue.
Waiting for PIDS: 686.

may i know of a simpler way to stop sendmail from being
enabled?

thanks,

~mayuresh
