[Dovecot] imap list response has an extra field on some mailboxes.

Hello,

per rfc3501

7.2.2. LIST Response

Contents: name attributes hierarchy delimiter name

Dovecot: 2.1.16

/usr/lib/dovecot/imap -u user@domain.tld

list "" "*"

Most responses are correct. But some appears to not be.

""" path/to/"part_mailbox_name" other_parts

• LIST (\HasNoChildren) "/" {117}

• LIST (\HasNoChildren) "/" {10} "test" box

"""

char after {117} appears to be \n.

All affected mailboxes appears to have ' " ' in mailbox name.

And the number between '{' '}' appears to be the length of the path.

Anyone ran into this issues before? If so, how to fix it? Is it a bug? Other rfc I should read?

Thanks Kui.Z
