Please add automatic return-path stamping and self service for the same.
Right now there is only one custom return path pr. sub account.
We should simply be able to setup this return-path once for a domain, and have is useable by multiple sub accounts
Just like with DKIM.
You can use plus addressing to make sure bounces are stored in the right subaccount.
Since many other vendors are doing this already, I expect to see the same form mailjet as it is essential for compliance and flexibility of the platform.
