Updated mediawiki/extensions
Project: mediawiki/extensions/BounceHandler  9ed9331e5937fc9dccd4f25b05a4a2b145fb34a2

Added API to handle incoming hard email bounces automatically

Exim should POST the bounce emails via curl using, the pipe config
command = /bin/curl curl -d "action=bouncehandler" --data-urlencode
"email@-" http://localhost/core/core/api.php
* This will call the API and pass the argument email to it, so that
details can be extracted for processing.
processIMAPEmails use public ApiBounceHandler::BounceHandlerActions.
* Added IP whitelisting to make sure only internal IP's are allowed to
perform the POST request using IP::isInRange()
* Make sure the API respond only to permanent bounces.
