Actually there are further problem with the INBOX namespace, to which I'm subscribed:

$ /usr/lib/dovecot/imap
S1: * PREAUTH [CAPABILITY IMAP4rev1 … MOVE NOTIFY SPECIAL-USE] Logged in as guilhem
C1: a1 LIST "" (INBOX TRASH) RETURN (SUBSCRIBED)
S1 * LIST (\Subscribed \UnMarked) "/" TRASH
S1 * LIST (\Subscribed) "/" INBOX
S1: a1 OK List completed (0.003 secs).
C1: b1 NOTIFY SET (SUBSCRIBED (MessageNew MessageExpunge FlagChange))
S1: b1 OK NOTIFY completed (0.002 secs).

$ /usr/lib/dovecot/imap
S2: * PREAUTH [CAPABILITY IMAP4rev1 … MOVE NOTIFY SPECIAL-USE] Logged in as guilhem
C2: a2 APPEND INBOX {1+}
C2: x
S2: a2 OK [APPENDUID 1384472528 26087] Append completed (0.008 secs).

This crashes S1 as well:

S1: imap(guilhem): Panic: file mail-storage.c: line 1511 (mailbox_is_subscribed): assertion failed: (box->list->subscriptions != NULL)
S1: imap(guilhem): Error: Raw backtrace: […]
S1: Aborted

This might be related to [0] as it is INBOX-specific as well: APPENDing a message to TRASH (to which I'm also subscribed) triggers the MessageNew notification as expected.

S1: * STATUS TRASH (MESSAGES 3407 UIDNEXT 113820 UNSEEN 1)

Hi list,

The NOTIFY extension (RFC 5465) works fine for mailboxes in the "virtual/" namespace, but it crashes the IMAP client when used with a mailbox in the empty "" namespace:

The "subtree" mailbox filter has the same problem, but the non-parameterized ones ("inboxes", "personal" and "subscribed") work fine.

You'll find the output of ‘dovecot -n’ enclosed. Cheers,
