Using cron job, it sends out the mail. Since cron jobs run as you.
From the web, it does not work for me. Silently fails. Since Apache runs as 'nobody' .
Might be because their mailserver screens the 'From' header (which is an account on my website which matches the user when run as a cron job, but is not 'nobody' when run as a web script).
Not sure if the Staff know or what their response is.
