And we only support rfc compliant imap servers :-)

it's sending the equivalent of:

LIST "" ""

this command is useful for getting the directory separator.

A0 LIST {0+}
_{0}
_

The above command is yet another way to do it (using _'s in place of
spaces to make it easier to see)

The reason the first is made into a {0+} is because we use the namespace
string (which could be anything) and so our code uses a %F (a made up
printf-style special) and when our code encounters that, it says "oh,
this IMAP server supports LITERAL+ so lets use that syntax" and it does.

the call is something like:

camel_imap_command (imap_store, NULL, "LIST %F \"\"",
imap_store->namespace);

or some such.

anyways, it is your imap server/proxy/whatever that is broken and we
have enough kludges around broken imap servers as it is without adding
more pain. Not to mention the current imap codebase is a complete mess
to work with.
