Thanks for this. I've been playing with it for a couple of hours. I've
always wanted to automatically verify new users to a mail list I
created. I'm sure you know what I mean. When they sign up I send an
automated email which they must respond to (leaving the subject
intact). This is going to work great (using cron to poll).

Have you any clever method for pulling lines out of the headers array?
Using explode at the :'s will not work because of the Date line (time
contains :'s), so I do this:
(just curious to know if there is a simpler way to do it)

for ($i=0; $i<count($headers); $i++)
{
// find first colon in the header line
$breakpos = strpos($headers[$i], ':');

// header field = substring from 0th character to breakpos
$field = substr($headers[$i], 0, $breakchar);

// set field = substring from breakpos to end of string
switch ($field)
{
case 'Date':
$date = substr($headers[$i], $breakpos);
break;
case 'From':
$from = substr($headers[$i], $breakpos);
break;
case 'To':
$to = substr($headers[$i], $breakpos);
break;
case 'Subject':
$subject = substr($headers[$i], $breakpos);
break;
}
}

I'm not going to bother with the "Received" fields.

Thanks, Manuel. You have lots of class ô¿Ô¬
