Setting a time to start delivery of an email

[kelvinj]

Hi,

I have a very specific requirement for a website I'm building.

Basically it requires that an email be sent via the site but with a
delay. For example, Joe Bloggs visits the site and performs an action
which triggers an email to be sent, but that email must be delivered
at 9am the following morning (don't ask :-) ).

So, I was thinking of building a simple queue manager and controlling
it from a cron job, but then I figured if postfix can handle this, it
would save me a bit of time.

Any ideas?

Cheers,
