Good evening,
I'm using courier-imapd 3.0.7 and procmail to filter and sort mail to different sub folders (via Maildir). New mail notification doesn't seem to be working unless I do a sync or click on the sub folder.
If your IMAP client doesn't check for new mail in subfolders, there's nothing the server can do about it. It's the IMAP client responsibility to check for new mail.
Hmm, I tried with Apple's Mail.app, Mozilla's client and Mozilla Thunderbird -- nothing worked. I have to imagine at least one of those clients checks subfolders...
Your imagination is too active for IMAP. Only the currently open folder can be constantly monitored for new mail. Other folders must be explicitly queried.
An IMAP client is not going to start flinging commands at the IMAP server every second, to check for new mail. That's rude.
At most, the IMAP client will check for new mail every couple of minutes.
An IMAP client can perhaps open another IMAP connection and open a second folder so that it can be monitored for changes. A separate IMAP connection will therefore be required for each monitored folder.
An IMAP client will not open twenty connections to monitor twenty folders for new mail. And even if it did, Courier-IMAP will prevent it from doing so.
Therefore, all IMAP clients will only monitor the currently open folder for new mail, at most.
