Check if notification is disabled

in send_smtp_message()
Other packages like arpwatch sm.php and cron job output as reported in forum https://forum.pfsense.org/index.php?topic=88347.0 call send_smtp_message() directly, currently bypassing notification disabled checks. I think those packages [are intended to | should be] respecting the notifications disabled setting. People in the forum certainly expect them to respect this setting....
