[patch] Missing To header

[Harri Porten]

Hi!

I occasionally got some PHP warnings after we enabled the e-mail routing
interface. They were triggered by (spam) e-mails with missing To headers
that made this check

  if (preg_match("/$prefix(\d*)@$mail_domain/i", $email->toaddress,
$matches)) {

from class.support.php trigger the notice: "Undefined property:
toaddress in /var/www/eventum/include/class.support.php on line 550". I
therefore suggest to either guard the check (see attached patch) or simply
add a statement like

  if (empty($email->toaddress))
     return false;

further above.

Harri.
