[Dovecot] Proxy and Virtual IMAP Folders

Hi all

I am a newbie to dovecot and I would like some help clarifying a feature to determine if I can use it in my project.

Is is posible to use the virtual plugin, in a IMAP proxy configuration, in a way that the virtual plugin searches messages on the real server?

Here's my scenario:

[Client]----[Dovecot Proxy]-----[Real Imap Server]

Client connects to Dovecot Proxy and gets all the folders that are on the Real Imap Server, plus some virtual ones (generated by Dovecot Proxy) that search for messages on the real server. In my config the Dovecot Proxy has no email messages, real folders, or local delivery.

I would like to thank you in advance for ant help and support.

All the best Pedro
