There is no imap-idle support in claws-mail and this feature seems will never be in claws-mail. I have about 50 different imap folders and I whould like to know when some folder gets new mail. Thunderbird does this by default - TB shows new messages in all subscribed filders immediately (idle support?). I tried notification plugin but it does not check new mail even in INBOX folder. Dovecot is used in server side. How it can be realised with current claws-mail featureset ? May be some plugin ?
