[Dovecot] 2.0/2.1 - different behavior for LIST-EXTENDED

Hi Timo,

We are sitting here wondering if this difference in behaviour between dovecot 2.0.17 and 2.1.3 is intended.

When you create a folder, subscribe to it and rename it (without changing the subscription) these are the behaviours:

For 2.0.17: . list (SUBSCRIBED) "" "*" RETURN (STATUS (MESSAGES))

• LIST (\Subscribed \NonExistent) "." "INBOX.test"

For 2.1.3: . list (SUBSCRIBED) "" "*" RETURN (STATUS (MESSAGES))

• LIST (\Subscribed) "." "INBOX.test"
• NO Mailbox doesn't exist: test

If you don't use rfc5819 the folder will just get silently ignored by dovecot 2.1.x, but if you actually try to get the number of messages you'll get the error.

It seems to me from reading rfc5258 that the 2.0.x behaviour is the correct ??
