Sparkpost Bounce Domain


New Member
We are using MailWizz with Sparkpost.
On sparkpost side we have multiple sending domains and for each sending domain we have a bounce domain.
When creating a delivery server in MailWizz there is no way to specify a bounce domain and when emails are being sent, the default bounce domain is being used.
How can we specify what bounce domain to use for each delivery server?
We tried using X-Force-Return-Path custom header but it did not work.
Sparkpost says it can be done on the transmission request (

Thank you.
Why do you need this? As long as you create the delivery server using the api integration, then MailWizz also creates the webhooks where to receive notifications and it also processes those notifications, which is all you need.
