similar to: doveadm sis deduplicate problem

http://hg.dovecot.org/dovecot-2.0-sis contains the code for it. Otherwise it's the latest (as of writing this) dovecot-2.0 hg tree. Please test if you're interested in SIS. :) Once there's at least some testing, I'll probably add this to v2.0.x since very little of this new code is used when SIS is disabled (which is the default of course). SIS works pretty much like explained in

Running Dovecot 2.2.25. I have the following line in my root crontab: "/usr/local/bin/doveadm sis deduplicate /home/dovecot/buzones/attachments /home/dovecot/buzones/attachments/queue" This line is execute each hour and the plan is to deduplicate attachments stored in the SIS system. This works well most of the time, but from time to time cron complains with this error:

Hi everyone, I am currently trying to setup our next dovecot server (2.2.18) with SIS enabled, but I have enconutered 1 problem and 1 question: *1) Same attachment, different filenames* I have a feeling a misconfigured something (or forgot to do something) because SIS almost works, but not quite since 3 identical attachment take 3x the space (see end of email for my SIS config).

How do you do. I have tried to use SiS to deduplicate attachments in mail storage. Unsuccesful. When goes mail with reasonable size, and SiS try to start, I have receive error, when this mail must be delivered for group of receivers (i.e. through aliases). Below is error log, valuable parts of mail addresses masked by X and Y chars Aug 6 16:11:12 mailsrv dovecot: lmtp(xxxxx):

Hi, I'm currently running a small home-server with Dovecot. A long time ago I configured it with SIS enabled. I would like to stop using SIS. If I remove sis from mail_attachment_fs will the old mails that are stored in SIS-storage still be accessible? How can I convert all mailboxes to stop using SIS and store attachments back in the mails? Rgds, N.

Hi all, I have noticed a strange behavior with dovecot (tested with 2.2.13). I use shared folders to share mailboxes between users. I have a namespace called "Accounts" that hosts the shared folder for the users (prefix Accounts/%%n/). However, When I issue an IMAP select command on a random non-existent mailbox name under "Accounts", dovecot auto-creates it and pollutes my

We will be deploying a replacement Dovecot server soon, and we are planning to use maildir for the primary storage, but with an archive namespace using mdbox (or perhaps sdbox), and SIS. Our backup servers and (luke)warm spare server need to obtain full copies of the mail store. For the maildirs I know I can simply use rsync (we already use it here). I'm a little wary of using rsync with

Hi, I've been working with dovecot SiS for a long time without any problem. This is my configuration for SiS: mail_attachment_dir = /mail/users/attachments mail_attachment_fs = sis posix mail_attachment_hash = %{sha1} mail_attachment_min_size = 128 k With this configuration, I have, for example: # ls -l /mail/users/attachments/27/d1/27d1904ac9947945bf48ea545ec278940d840ed1* -rw-------
