IMAP e-mail updates even after turning off automatic updates.
 

Am I doing something wrong or is there a bug with automatic e-mail updates settings?
I have turned off automatic updates last night, so that the sound of the new mail doesn't bother me, but new e-mails were still coming in, so I had to turn off the sound for the e-mail notifications.

Is there a way to specify the times for e-mail synchronization?
