This can be bit tricky, as from the headers, we can readily take out the recipient's email (would be in the To:), and then notify him using Echo, but notifying the actual sender would not work that way. I am not sure if we can regex through a wiki email and find out the actual sender. </div><div class="gmail_extra"><br></div><div class="gmail_extra">Currently we notify a user only when emails to his account bounce more than a threshold (5, as I remember), right after we un-verify the accounts email id. The user is asked to re-verify again in the notif, and if one more email to that user bounce, he is unsubscribed again. Since we do a select count(*) and check if its > threshold, the second time he already has a threshold > 5, so that condition is met. We prune the records which are 90 days old, so before that, its very easy to get unsubscribed again!</div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div>Thanks,</div><div><a href="https://www.mediawiki.org/wiki/User:01tonythomas" target="_blank">Tony Thomas</a></div><div><a href="http://www.thomastony.me" target="_blank">Home</a> | <a href="http://blog.thomastony.me" target="_blank">Blog</a> | <a href="http://www.thinkfoss.com" target="_blank">ThinkFOSS</a><a href="http:///" target="_blank"></a></div><div><br></div></div></div></div></div></div></div></div></div></div></div></div></div>
