Dovecot 2.2.5
In selected state:
C: 1 SELECT &#-&#/#
S: 1 NO Mailbox name is not valid mUTF-7
S: * OK [CLOSED] Previous mailbox closed.
I can verify that this only seems to happen when the mailbox name is
incorrect mUTF-7. Things work fine if I access a non-existent mailbox:
C: 1 SELECT non-existent-mailbox
S: * OK [CLOSED] Previous mailbox closed.
S: a NO Mailbox doesn't exist: non-existent-mailbox
FYI: Switching to Dave C's workaround discussed here --
http://mailman2.u.washington.edu/pipermail/imap-protocol/2005-September/000053.html
-- regarding servers that don't support UNSELECT. This would normally never
happen on Dovecot since it supports UNSELECT; I'm intentionally ignoring
that capability for testing
purposes.
I'm not pipelining a CLOSE with the above SELECT command, like Dave
suggests, because the likelihood this SELECT will be successful is
about zero and I'd rather avoid a BAD response to a CLOSE command,
since it is plausible that a server could issue a CLIENTBUG response
for a client that is trying to CLOSE a mailbox in Authenticated State.
(Granted, a server could also plausibly issue a CLIENTBUG for
identifying a mailbox in incorrect mUTF-7 also, but whatever.)
