XF 2.0 Not getting bounce notifications

[Mr Lucky]

I am using mailgun SMTP

I have a (valid) bounced email address in xenforo email options

However when I send an email to a test user that I know has an address that will bounce, I get no bounce notifications, neither by email nor in the bounce log.

( I do see a fail in the mailgun logs)

Does anyone know what might be going wrong?

Thanks

If you send a test email to yourself, can you look at the "raw" email headers and see what the "Return-path" is indicated as? This is where bounce messages will be sent. It's possible Mailgun is changing this from what XF tries to set in which case, that will interfere with our bounce processing.

 

[Mr Lucky]

Return path=

Return-Path: <bounce+e60d7f.5f5134-admin=cafesaxophone.com@mg.cafesaxophone.com>

Is your bounce address set in XF as bounce@mg.cafesaxophone.com? If not, then that has definitely been changed. However, even if it is, I don't think that is how we set the VERP value for this, so I think Mailgun is manipulating that (probably into a system where they can process it). Unfortunately, that is likely to cause issues with XF doing bounce processing.

No I don't use the mg subdomain at all (just for the default address which is noreply@...)

The bounce email address is my own personal address and is not showing at all the return path.

Aha, did a search and it looks like I asked almost the same question almost a year ago:

XF 2.0 - Not getting bounce notifications

I have set up an address in Bounced Email Address, but am not getting any notifications (nothing in bounced email log either). Any idea what I might be doing wrong? (Presumably there's no point in setting up Enable automated bounced email handler until I get the basic notifications working?)...

Plus I found this also

Not a bug - smtp.gmail.com wants OAuth 2.0

Trying to set up gmail smtp forum.example.com/admin.php?options/groups/emailOptions/ Email transport method: smtp (smtp.gmail.com : 587) Authentication - no OAuth 2.0 option Encryption: TLS Apparently Gmail really wants OAuth 2.0 - support would be nice. Current workaround...

OK, just did a test using default email transport instead of mailgun and I got the bounce notification (and the return path for a test send to myself showed just the bounce email address, so that seems to be fine)

BUT

Nothing in the bounce logs (after running cron Process bounced emails)

If you received the bounce notification, that likely means that you've read it. There are a few different setups here and mail server variables, but it's unlikely that the bounce processor will process any message that has been seen before (as this is how it skips dupes) -- it would really depend on how the mail server treats our requests specifically.
