Dear Support,
Emails are being sent out, opens & clicks are traced perfectly, however bounces are not showing up for some reason.
I have run a couple of small tests with 4 real email addresses and 2 fake email addresses, however everywhere I look it says 6 sent with success and 0 bounce results. Somehow, I also do not receive any bounced emails at the email address either.
When I ran a full-size campaign with 100k+ subscribers, I did receive 1000's of bounced reports at the reply to email address however once again I didn't see anything in the bounced reports. Furthermore, the bounced emails were actually email addresses that I verified again after and these addresses are verified and existent through multiple tools. An example of the bounce messages is:
Subject: Undelivered Mail Returned to Sender

The bounce-server does not get stuck on cron-running, the emails are delivered to any test email address I use (gmail/live/company) so I personally have no idea where to look for issues.
