In general, Courier supports the capability check, but your particular installation may have been built/configured to not support that. I'm not sure why, unless someone was being really stingy and didn't want the capability support code in their imapd memory footprint...

	Eric,

Thanks. I asked around, we are using courier and are not sure whether
courier IMAP supports the capability chekc or not. Each time I run it
on our server, I get a blank list of results.

HOWEVER, I went in and commented out the four checks for "SORT" - 2
in rcube_imap.inc, 1 in func.inc, and 1 in show.inc. Now that I have
commented out the checks for "SORT" support (in both beta2 and svn) I
am able to sort correctly by any of the columns at the top and in any
order (ASC or DESC).

So, in short, I dont get a response from the CAPABILITY check for
either QUOTA or SORT support, but I have commented out the portions
of code for those checks and I am able to use both in RC (again, Beta
2 and SVN 317).

Thanks,
Kevin L.
