Hi,
I hope, this is the correct channel to ask my question.
We discovered a very strange Bug on cyrus-imapd/oldstable,now 3.0.8-6+deb10u6 amd64 (Plain Debian Buster). Mail Clients, especially Thunderbird, must be restarted to see new (recent) Messages.
With help from trustworthy Wireshark and "openssel s_client" I could break the effect/bug(?) down to some strange behavior:
- With an active IDLE command, RECENT notifications won't get pushed to the client. IDLE won't
send any notifications. - SEARCH ALL or UID SEARCH ALL wont report newly arrived messages
- Your have to perform a SELECT INBOX (or any other folder) to get new messages. After sending
SELECT INBOX both command (SEARCH and UID SEARCH) will report RECENT messages.
Is this a bug? A configuration error? Anyone got same effect? Any advice?
Greetings
Jörg
