Hi,

I'm becaming crazy about this!

I've asked before, not no matter what i do or conf, never works.

How can i make IDLE work for real with MSOutlook, so that i can receive emails when they arrive, instead of changing folder/get out and in my account?

Here's my conf, should it be reflected in postconf -n (is it the running conf?):

==================

root@fastmail:/etc/dovecot# grep -ir idle *

conf.d/20-imap.conf.ucf-dist:# If nothing happens for this long while client is IDLEing, move the connection

conf.d/20-imap.conf.ucf-dist:# IDLEing.

conf.d/20-imap.conf.ucf-dist:#imap_idle_notify_interval = 2 mins

conf.d/20-imap.conf:imapc_max_idle_time = 1440 mins

conf.d/20-imap.conf:# IDLEing.

conf.d/20-imap.conf:#imap_idle_notify_interval = 2 mins

conf.d/20-imap.conf:imap_idle_notify_interval = 1 min

conf.d/20-imap.conf:#imap_client_workarounds = outlook-idle

conf.d/10-mail.conf.ucf-dist:# When IDLE command is running, mailbox is checked once in a while to see if

conf.d/10-mail.conf.ucf-dist:#mailbox_idle_check_interval = 30 secs

conf.d/10-mail.conf:#mailbox_idle_check_interval = 30 secs

root@fastmail:/etc/dovecot# postconf -n|grep -i idle

root@fastmail:/etc/dovecot#

Can you provide doveconf -n? Have you followed this https://doc.dovecot.org/configuration_manual/hibernation/

Aki Tuomi

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

Here's my conf, should it be reflected in postconf -n (is it the running conf?):

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

conf.d/10-mail.conf:#mailbox_idle_check_interval = 30 secs

root@fastmail:/etc/dovecot# postconf -n|grep -i idle

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

root@fastmail:/etc/dovecot#

Hi again,

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

I just read again the mails you sent and realized it had nothing to do with hibernation. Sorry about that..

imapc_max_idle_time = 1 days

this is related to imap client, not imap connections. it won't really matter for your issue.

also I note that you have disabled SSL and enabled plaintext authentication over insecure channels, is this intentional? For debug purposes you can use rawlogs feature, which is better for this.

https://doc.dovecot.org/admin_manual/debugging/debugging_rawlog/

In fact, you could use this feature to find out whether outlook even tries to use IMAP IDLE in the first place.

Dirst, others have asked but I haven’t seen an answer, do you have any reason to think Outlook supports IMAP idle at all? I mean, I know outlook.com doesn’t support it, so maybe it just doesn’t work?

Secondly, assuming Outlook does support IMAP idle, if you setup Dovecot to use SSL and not stunnel do things work?

Yes, it works with other IMAP servers, why should not work with dovecot? It was working with DBMail, and it's working with an account from my Telco that used cirus-imap.

Have you verified (with rawlogs or tcpdump) that outlook even attempts IDLE? Is your dovecot advertising IDLE support in CAPABILITY?

Sami

Well,

I've been doing some research, and it seems that msoutlook 2016 and 2019 doesn't quite have imap idle support. The odd part, is that when i had DBMail, it was IDLE'ing (i swear), Would dbmail send something different that make it work? It was an old version of dbmail, 2.3.7 i believe, from about 2012 or so.

And no, it wasn't the outlook options "send/receive", i had and have that disabled,

Don't have explanation, thunderbird IDLE's perfectly

When i migrated the account from the old imap server to the new (dovecot), i didn't removed and created the account in msoutlook, as i didn't saw any reason to do it. Creating the account again, IDLE works ok!

Glad you got that figured out. Seems like a weird one.

I’m confused by your answer, how do your dovecot settings and/or use of stunnel affect other IMAP servers?
