I need to run a mail-migration from a Dovecot with mail_attachment_dir / single instance storage enabled. As mailboxes and mail_attachment_dir are rsynced I would normally run a doveadm backup -u <user> -R -d dbox:<path to rsynced mailbox>/dbox How can I tell it the mail_attachment_dir the rsynced source / (reverse) destination uses? Or do I have to st...

Hello, we have 2 netapp arrays with 2 volumes and we need to store our mail data in one or other volume for every user. We want keep data for one user in one volume only. So we would like to have 2 separate mail_attachment_dir, one on every volume. But in latest version 2.2.12 it look like it is only possible to set one global mail_attachment_dir. I have an idea with 2 separate dovecot instances per machine with different mail_attachment_dir. Or it is possible to somehow specify it per user ? Thanks -- [ Ohodnotte kva...

Hello everybody, What is the best way to delete an user mailbox (ex: /var/mail/johndoe ) when all attachments (for all users) are in a common directory with SIS deduplication (ex: mail_attachment_dir = /var/mail/attachments ) ? Trying to delete user mailbox directory (rm) and do the command : doveadm -v purge -u johndoe leave all johndoe's attachments orphelin. Best regards, TN

Hi there ! I?m using dovecot 2.3.10 (manually compiled on Centos 8 x86_64 - fully updated), XFS filesystem, with mdbox and a separated compressed attachment directory: mail_attachment_fs = sis compress:lz4:6:posix mail_attachment_hash = %{sha256} mail_attachment_dir = /ATTACHMENTS I'm using dovecot LDA (for mail delivery). Everything works fine with the delivery and compression. The first test, I send one tar file with 7Mb. It was correctly compressed (2791959) and stored in mail_attachment_dir. But when I tried to access it via IMAP ( thunderbird/evoluti...

Hello, I don't find any indication, that no btrfs for then filesystem for the path in "mail_attachment_dir" is to be used. but btrfs has a big problem with hard links in the same directory. Nuisance is the only deal with a different file system? Hardy

Was trying to set up attachment storage, but folders are receiving permission only for current user, so if another user is receiving a mail with same attachment he is getting permission denied error on reading hash file. Is it possible to setup global attachment storage to work with all users, at least in domain? mail_access_groups won't help, as folders are given 0 group permission. Umask and

Hello, I have a Dovecot setup where I need to allow users to access a snapshot of their messages (when they complain about missing messages/folders deleted by mistake). From time to time the system does a LVM snapshot of the volume holding the mailboxes and sis storage and that messages are available via a "special" namespace. The problem is the messages that references

...o that all my different users can share the same pool of attachments? Alternatively, is it possible to have dovecot save the attachment under more flexible permissions so that they can be shared between users? This would allow us to save alot of disk space. *Here is the SIS config I am using:* mail_attachment_dir = /data/emails/attachments #mail_attachment_min_size = 128k #mail_attachment_fs = sis posix #mail_attachment_hash = %{sha1} Any help would be very much appreciated. Thank you, Joe B

I am running dovecot 2.0.13 on CentOS5, set up with only local system users, and single instance store set up in a single directory. e.g. mail_attachment_dir = /var/mail/attachments I get errors when importing mail to IMAP because the attachment directories are owned by the respective mail account user(s) and so cannot be accessed or written to by other users. Are there some user id setting I need to change, or do I have to run dovecot with virtual u...

...tance storage feature, so I'm posting my questions here. - Are these 3 parameters the only one necessary for single instance storage? I cannot find any doc on this feature on the website; is there anything specific I need to know about them? (the last one isn't exactly self-explanatory). - mail_attachment_dir = /srv/vmail/attachments - mail_attachment_hash = %{sha256} - mail_cache_min_mail_count = 2 - Is this feature ready for production? Thanks, -JD

Hi. Well, I've the next problem. I turned on the new attachment de-duplication stuff in the configuration. If I send an attchment between two accounts on my test system, the attment gets saved ion the configured mail_attachment_dir. But... if I delete it from the senders Send folder and the receivers Inbox (and of course empty Trash afterwards in both cases), the hashes and the attachment are not deleted in mail_attachment_dir (as I would expect). Is this a bug, or have I misunderstood the concept of storing attachments? R...

Hello, In mdbox SiS POSIX mail box setting - There are hard-links under - <mail_attachment_dir>/ha/sh/<hash>-<guid-1> <mail_attachment_dir>/ha/sh/<hash>-<guid-2> Why is a copy of the file kept under hashes/<hash> ? -- Regards, Sai Kiran

I think it would be very useful to have a user's GID in a variable. So i could use for example: mail_attachment_dir = /srv/mail/.SiS/%{gid} I use one GID per domain and the aliases fqhns of the domain. When for example example.com would be an alias for exmaple.net (gid: 12345), the attachments would be stored inside /srv/mail/.SiS/12345/, no matter if a message was sent to john.doe at example.com or to john.doe...

Hello, We are migrating our dovecot servers from 2.1.9 to 2.1.15 (or 2.2 if there is a stable version soon) and maildir format to mdbox. Looking for mdbox options I have found options: * mail_attachment_dir * mail_attachement_min_size * mail_attachment_fs * mail_attachment_hash but this options are described with the message: # WARNING: This feature hasn't been tested much yet. Use at your own risk. What is the state of these options? Could I use it in a production environment? In case of ye...

Ok, didn't find much on this... The bottom of /etc/dovecot/conf.d/10-mail.conf has the following settings: #mail_attachment_dir = #mail_attachment_min_size = 128k #mail_attachment_fs = sis posix #mail_attachment_hash = %{sha1} all of which are apparently the defaults according to doveconf -d output - so no need to set them explicitly, unless I want to change them, right? So, enable the first one - but - the comments don&...
