I've decided to have a play and have installed the INFO plugin into SquirrelMail. This allows you to run IMAP commands and see the results. Looking at my logs above the error occurs just after: 00:14:07.125: >> A005 APPEND "" (\Seen) {1369}<cr><lf> 00:14:07.125: << A005 NO [TRYCREATE] No such folder.<cr><lf> So I ran the command within SquirrelMail / Info: APPEND "" (\Seen) {1369} This resulted in: Request: A003 APPEND "" (\Seen) {1369} Response: [TRYCREATE] No such folder. Mecury Logs showed: 16:48:39.937: << * CAPABILITY IMAP4rev1 AUTH=PLAIN X-MERCURY-1<cr><lf> 16:48:39.937: << A002 OK CAPABILITY complete.<cr><lf> 16:48:39.937: >> A003 APPEND "" (\Seen) {1369}<cr><lf> 16:48:39.937: << A003 NO [TRYCREATE] No such folder.<cr><lf> 16:48:39.937: >> A004 LOGOUT<cr><lf> 16:48:39.937: << * BYE IMAP4rev1 server terminating connection.<cr><lf> No such folder... So I changed the command slightly: APPEND "INBOX.Sent" (\Seen) {1369} INBOX.Sent being my sent folder This resulted in what looked like SquirrelMail freezing.. But Mercury Logs showed: 16:52:26.031: << * CAPABILITY IMAP4rev1 AUTH=PLAIN X-MERCURY-1<cr><lf> 16:52:26.031: << A002 OK CAPABILITY complete.<cr><lf> 16:52:26.031: >> A003 APPEND "INBOX.Sent" (\Seen) {1369}<cr><lf> 16:52:26.031: << + Ready to receive 1369 bytes<cr><lf> So something happened !! I don't think SquirrelMail is detecting the sent folder correctly. Looking in functions/IMAP_general.php we have: /** * Saves a message to a given folder -- used for saving sent messages */ function sqimap_append ($imap_stream, $sent_folder, $length) { fputs ($imap_stream, sqimap_session_id() . " APPEND \"$sent_folder\" (\\Seen) {".$length."}\r\n"); $tmp = fgets ($imap_stream, 1024); sqimap_append_checkresponse($tmp, $sent_folder); I editted this to read: fputs ($imap_stream, sqimap_session_id() . " APPEND \"INBOX.Sent\" (\\Seen) {".$length."}\r\n"); And.... it WORKS. :) Read Receipt is sent, SquirrelMail refreshes correctly and the sent receipt is shown in INBOX.Sent. So this appears to be a bug !! But at least this appears to be a quick work around !! -- View this message in context: http://www.nabble.com/Read-receipt-errors.--TRYCREATE--tp17302421p17304527.html Sent from the squirrelmail-users mailing list archive at Nabble.com. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
