When i try delete one or severals messages, appears the notification: "Error when communicating with the server" In Kronolith this error it's solved in this ticket: http://bugs.horde.org/ticket/9818 But i dont find any information about imp Thu, 14 Apr 2011 18:25:15 +0000 https://bugs.horde.org/ticket/9915#t63753 Check the Horde and/or IMAP logs. For further debugging information, please read the 'AJAX Troubleshooting' section in imp/docs/INSTALL. Thu, 14 Apr 2011 19:11:54 +0000 https://bugs.horde.org/ticket/9915#t63760 I'm facing the same problem. Sometimes when deleting mail I do get the said error. IMAP log (dovecot here) shows: 2011-04-16 09:50:37 IMAP(theuser): Info: Connection closed bytes=101/996. Horde didn't write any logs. Sat, 16 Apr 2011 07:53:43 +0000 https://bugs.horde.org/ticket/9915#t63829 I see the 'Error when communicating with the server' as well. But it appears/happens really randomly and not very often. I haven't found a way to reproduce. I use courier-imap 4.8.1 $_prefs['use_trash']['value'] = 1; $_prefs['delhide']['value'] = 1; For the following trace, I was using dynamic view, and deleting a few selected messages. 2011-04-18T09:13:40+02:00 ERR: HORDE [imp] IMAP error: Error in IMAP command received by server.

This could be related to the IMAP server (I guess, I'm no expert). Mon, 18 Apr 2011 08:46:26 +0000 https://bugs.horde.org/ticket/9915#t63842 I have the error , although i delete only a message. Im using dovecot as imap server, and postfix as mail software. The message is deleted, but appears the notification... When i using traditional mode, appears blank page when i delete a message.

Mon, 18 Apr 2011 22:45:05 +0000 https://bugs.horde.org/ticket/9915#t63867 > "Error when communicating with the server" This error by itself doesn't mean anything - it simply means that the AJAX response from the server was broken, most likely because the server fatally exited on an error. So you must look at the Horde log to provide any useful information.

This could be related to the IMAP server (I guess, I'm no > expert). It looks like there is an issue with calcualting the UID list after an EXPUNGE response. Jan (and I) are probably not seeing this because the VANISHED response is being used instead.
