Hi,
Is BounceHandler able to be used alongside an external SMTP server configured using $wgSMTP? In terms of receiving the POST upon bounced emails, we can configure the SMTP server to POST using events, but I'm unsure if BounceHandler is able to set the Return-Path header on outbound emails when an external SMTP server is used? Thanks
BounceHandler requires a modification in the mail server, to route bounced emails to a special queue that triggers an HTTP POST request to the MediaWiki api.
You can't do that on an external mail server.
Technically, you should be able to use it with a 3rd party SMTP server. I remember setting this up with Mailgun, back during development. Extension:Mailgun
Now, the trick is in the hook implementation of UserMailerChangeReturnPath, and from the code here: https://github.com/wikimedia/mediawiki-extensions-BounceHandler/blob/master/includes/Hooks.php#L44 , I can see that you can form custom "Return-To" emails by setting variables correctly in your configs.
