Package: cyrus-imapd Version: 3.0.11-1~bpo10+1 Severity: important Dear Maintainer,
I installed a fresh buster for reproduction. I tested with cyrus-imapd version "3.0.8" from buster and "3.0.11" from stable-backports. Create user "imapuser" with password "password" User created 3 folders: - INBOX/foo - INBOX/foo/1 - INBOX/foo-1 imap command '. list "" * ' marks folder "foo" as HasNoChildren. root@debian-buster:~# telnet localhost 143 Trying ::1...

OK Completed (0.000 secs 2 calls) Because of the "\HasNoChildren" some clients fail to select subfolder INBOX.foo.1 The code seems to depend on the order of mailboxes and sets "HasChildren" on the previous Entry if the current entry is a child. -- System Information: Debian Release: 10.0 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-5-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages cyrus-imapd depends on: ii cyrus-common 3.0.11-1~bpo10+1 ii dpkg 1.19.7 ii libc6 2.28-10 ii libcom-err2 1.44.5-1 ii libsasl2-2 2.1.27+dfsg-1 ii libssl1.1 1.1.1c-1 ii libwrap0 7.6.q-28 ii zlib1g 1:1.2.11.dfsg-1 Versions of packages cyrus-imapd recommends: ii rsync 3.1.3-6 cyrus-imapd suggests no packages. -- no debconf information
