Nice! I'll have to look into this library some time. How do you
control it to prevent sending the same message though? I can't imagine
this is called from a web page, because I'm guessing it would take a
few minutes to finish. If it's called from a cron job, don't you still
have to somehow flag the message as having been delivered so that the
next process doesn't come along and send the same thing all over
again?
