Bounce(NDR) processing in MailWizz + KumoMTA

KumoMTA Integrations
1

Hi all,
I am trying to do bounce processing where KumoMTA will have to send the bounce DSN emails to my bounce processing mailbox.
Mailwizz will read from the bounce server/mailbox through IMAP and unsubscribe.

But, the bounce DSN/NDR emails are not delivered to the bounce/mail-from/return-path address given in the SMTP transaction.

Is there any extra configuration that I have to do in KumoMTA configuration files?
init.lua (6.11 KB)

if you use the RFC_3464 generator, you can also modify the message to change teh FROM address if necessary.

Webhook is better and more faster, you just have to code Mailwizz PMTA behaviours inside lua. After that, create a delivery server via Mailwizz and choose pmta.

Then use the provided webhook on kumomta.
