I have been testing xfer of accounts within a cyrus murder from 2.3.15 backends to new 2.4.17. backends. all the email and folders seem to migrate perfectly and the xfer'd accounts can send and receive email. However when reading email with an IMAP client I am having strange issues setting flags within folders on messages. In particular setting and unsetting deletion flags is very erratic. In some folders it doesn't work at all, on others I can set the deletion flag but can't unset it. All of the backends have delayed expunge switched on. debug output from the alpine IMAP client seems to suggest the server is doing what it's told: IMAP DEBUG 12:04:30 5/7: 01000069 STORE 93 +Flags (\DELETED) IMAP DEBUG 12:04:30 5/7: 01000069 OK Completed IMAP DEBUG 12:04:31 5/7: 0100006a STORE 94 +Flags (\DELETED) IMAP DEBUG 12:04:31 5/7: 0100006a OK Completed but then something seems to immediately remove the flag, because on issuing an expunge the client finds nothing to expunge. nothing of note seems to be logged on the backend, even logging in debug mode. the other baffling thing is that in some folders within the same users account, this whole process works perfectly. does anyone have any ideas what could be causing this and if there might be a solution? many thanks, Gavin Gray Edinburgh University Information Services Rm 2013 JCMB Kings Buildings Edinburgh EH9 3JZ UK tel +44 (0)131 650 5987 email gavin.gray@xxxxxxxx -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336. ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
