Not getting a desired result + (plus) address with / (slash) to a nested folder

When email inbound+test@domain.com the email are correctly placed in a subfolder to the inbox.

However, when I am using a / (slash) to route emails to a nested folder, for example: inbound+test/nested@domain.com it is delivered to the Inbox folder.

Is nested folder plus addressing a non-supported feature?

Not be default.

You have to go into the Dovecot conf file and edit this feature.

There are guides online with a simple Google search.

But as always, do a backup before making any changes like this.

Brilliant. Thank you for your time and effort.

I will have a deeper look into this.
