I was using this, indeed. As soon as I disabled it the interface became
more responsive due to the number of IMAP connections dropping. However,
once disabling this option Horde stopped checking for new mail every 5
minutes, as set up.
Is it me misunderstanding this feature? When capturing the traffic to
the IMAP server with "Notify on new mail" enabled I saw Horde
authenticating and polling each IMAP folder like this for every click:
. STATUS "INBOX" (RECENT)
. STATUS "INBOX.zzz-lists.horde" (RECENT)
... and so on.
How is this new mail feature working?

In the "Authentication Settings" page I have $conf[auth][params][app]
set to 'imp', which looks like it's using IMAP. We're trying to set up
Horde/IMP to access frontend Dovecot IMAP servers acting as POP/IMAP
proxies for Courier-IMAP servers running in the backend. Dovecot
doesn't store the credentials, but passes the authentication request to
the appropriate IMAP server, based on the pair "username <> backend
What other options do we have for our scenario to further improve the
