I configured hibernation as suggested by Aki, and still nothing.
What may i be missing?

I meant to past dovecot and not postfix, doing simultaneously stuff ends up
in this!
Yes, i migrated from DBMail and it was working OK.

Here it is:

root at fastmail:/etc/dovecot# doveconf -n|grep -i idle
imap_idle_notify_interval = 1 mins imapc_max_idle_time = 1 days
root at fastmail:/etc/dovecot#

Microsoft's Outlook is primarily meant as the client for Exchange. IMAP is
been poorly implemented, across many generations of Outlook. So are you sure
your Outlook even supports IMAP IDLE? And if it does, not only on the single
folder you have a running connection to but for all folders?

Postfix has nothing to do with that, so "postconf -n" is not required.

"doveconf -n" would tell you which settings are effectively set.
