[Dovecot] Problem in LSUB?

[Sergio Villar Senin]

Hi guys,

I'm not 100% sure about the dovecot version in the server because I
don't have access to it, just an account, but I think it's 1.1-rc4

I'm an email client developer and I have a doubt about the behaviour of
LSUB that I think it's buggy. See this chat with the server

My question is, why "LSUB "" INBOX" does not return anything while "LSUB
"" INBOX*" does ?
