Hi!

I know the topic of IMAP sorting has sort of died down, but I'm still having a problem with it. I'm using hMailServer on Windows. Here's what appears to be happening in the IMAP conversation:

"RECEIVED: cp01 CAPABILITY" "SENT: * CAPABILITY IMAP4 IMAP4rev1 QUOTA SORT[nl]cp01 OK CAPABILITY completed[nl]" "RECEIVED: a001 LOGIN my@email.com "password"" "SENT: a001 OK LOGIN completed[nl]" "RECEIVED: sel1 SELECT "INBOX"" "SENT: * 44 EXISTS[nl]* 0 RECENT[nl]* FLAGS (\Deleted \Seen \Draft \Answered \Flagged)[nl]* OK [UIDVALIDITY 0][nl]* OK [PERMANENTFLAGS (\Deleted \Seen \Draft \Answered \Flagged)][nl]sel1 OK [READ-WRITE] SELECT completed[nl]" "RECEIVED: srch1 SEARCH ALL UNDELETED" "SENT: * SEARCH 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44[nl]srch1 OK Search completed[nl]" "RECEIVED: s SORT (DATE) US-ASCII ALL UNDELETED" "SENT: s BAD Unknown or NULL command[nl]"

RoundCube then resorts to sorting the messages itself... I guess the question is.. why is Roundcube sending "s SORT (DATE)..."? What is this 's'?

Is anyone else having this problem? I looked in the code at imap.inc and I think the related code is around line 653:

$command = 's '. $is_uid .'SORT ('.$field.') '.$encoding.' ALL'."$add\r\n";

Any help getting this resolved would be greately appreciated!
