here is my config to enable the new function:
----
imap_hibernate_timeout = 60s
service imap-hibernate {
   unix_listener imap-hibernate {
     user = vmail
   }
}
service imap {
   unix_listener imap-master {
     mode = 0666
   }
}
----

using this settings, one thunderbird connected to an otherwise idle mailbox, I have there processes:
10312 ?        Ss     0:00 /usr/sbin/dovecot -F
10316 ?        S      0:00  \_ dovecot/anvil [10 connections]
10317 ?        S      0:00  \_ dovecot/log

10377 ?        S      0:00  \_ dovecot/imap-login [1 connections (1 TLS)]
10379 ?        S      0:00  \_ dovecot/imap-login [1 connections (1 TLS)]
10382 ?        S      0:01  \_ dovecot/imap-login [1 connections (1 TLS)]
10385 ?        S      0:01  \_ dovecot/imap-login [1 connections (1 TLS)]
11744 ?        S      0:00  \_ dovecot/ssl-params
11746 ?        S      0:00  \_ dovecot/lmtp

is it OK that there are still 10 separte imap-login processes?
are there concerns setting the mode for /var/run/dovecot/imap-master from 0600 to 0666?
and are there suggestions for imap_hibernate_timeout?

Thanks,
Andreas
