Need detail clarification about bouce server


New Member

I install mailwizz in server A to send using Server B, C, D via SMTP. In the Server B,C,D im using PMTA for IP rotations. In my bounce server, i set the server B domain and assign to Server B Smtp, server C domain and assigned to Server B smtp..etc..

In all my campaign, i set from using Server A domain example: and reply is their own gmail or personal account. But the actual bounce, it send to from Server B.

My Questions:
1. Should the bounce email send back to whichever server it send from?
2. The bounce email is jammed in my exim email queue, is that why the bounce report not accurate?
3. how can i better configure it to maintain using server A (from) and bounce back to which ever sending server and accurately get the data?
