After setting imap_hibernate_timeout to 60s, I could not find any hibernated connections after a few hours. I tested hibernation and made an observation: IDLE'd imap sessions only hibernate if they don't have a mailbox SELECT'd, otherwise they never hibernate. Is this the way it's supposed to work?

So for example if your imap processes are running as vmail user, you should set service imap-hibernate { unix_listener imap-hibernate { user = vmail } }. Then again if you are using system users (or otherwise multiple UIDs) it gets more

...t's rarely used though. - COMPRESS: The [de]compression code would need to be moved to login process instead of being done in imap-compress plugin. This would be a larger change, although it's also useful for various other purposes. The hibernation can be enabled for now simply by setting imap_hibernate_timeout setting to non-zero, which controls how long to wait after client has issued IDLE (and nothing happens) until the process hibernates. Some future work might include: - Moving the hibernation all the way to the first Dovecot proxy layer to avoid the need for imap-hibernate process at all. (Also m...
