track links do not works for expired emails

[snarchio]

The situation is this

• I have set the 'expire-days' => 60
• An user have an old mail generated more than 60 days ago
• User clicks on a link in the mail with tracking but the system does not find the tracking and redirects to a default url ('redirect-missing-links-to' => '/')

In my opinion the right behaviour must be that the user can reach the intended link even if the tracking is expired

A solution could be that in MailTrackerController -> linkClicked(...) at the bottom change return redirect(config('mail-tracker.redirect-missing-links-to') ?: '/'); to return redirect(config('mail-tracker.redirect-missing-links-to') ?: $url);

This is actually the intended behavior ... the security issue is that without the validation that the link was in the email then someone can create a malicious link through your website to redirect to an attack website. Unfortunately, you will need to extend the expire-days value or create a page that describes that the link has expired.
