Thanks very much for this! We applied this patch this morning and Pine 
is now behaving itself.

On the down-side, our quota scripts using Cyrus::IMAP::Admin have 
stopped working as they are not being sent MAILBOX-REFERRALS in the 
CAPABILITY string. This means they are ignoring the referral sent to 
them by the server when they issue a GETQUOTA. Reading RFC 2193 Section 
3, paragraph 1 this is understandable:

    IMAP4 servers that support this extension MUST list the keyword
    MAILBOX-REFERRALS in their CAPABILITY response.  No client action is
    needed to invoke the MAILBOX-REFERRALS capability in a server.

I feel like we've picked at the thread of a jumper and it's slowly 
unravelling here!

Regards,


Dave.
