# dovecot-related content below, this one for debian bug tracking # system: retitle 435959 Please support RFC4315 UIDPLUS extension in APPEND reply severity 435959 wishlist thanks
[please keep [EMAIL PROTECTED] on Cc.] Hi there, I am working on http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=435959, which is a performance problem that offlineimap has on large mailboxes. We think that a simple patch to dovecot could cure this problem. I am willing to write the patch but would really like to get your opinion first. In order to keep track of which IMAP message is stored in which local file, offlineimap uses the message UID, which is guaranteed to be unique in the directory, but constant across sessions. When uploading a new message to the IMAP server with APPEND, offlineimap then has to run a SEARCH to obtain said UID for the message it just uploaded. This takes ages on larger mailboxes, as the way offlineimap identifies the message is via a header that's not indexed by dovecot. The solution I found in RFC4315 ("UIDPLUS"; http://www1.tools.ietf.org/html/rfc4315) and then I saw http://www.dovecot.org/list/dovecot/2004-July/003993.html, and now I am wondering: is anyone else interested in APPENDUID? What's the status of an implementation, if any? Newer Courier IMAP server implementation support UIDPLUS and offlineimap will likely obtain this functionality soon.
