What happens if this setting gets changed - after the system has been running for some time? Are the old attachments lost? -- Daniel

...cot 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

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 yes, what is the best deduplicating option? Let it to the FS? Or configur...

Hi Guys, I am wondering about mail deduplication. I am looking into the possibility of seperating out all of the message bodies with multiple parts inside mail that is recived from `dovecot` and hashing them all. The idea is that by hashing all of the parts inside the email, I will be able to ensure that each part of the email will only be saved once. This means that attachments & common

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------- 12 vmail vmail 142914 may 6 2013 /mail/users/attachments/27/d1/27d1904ac9947945bf48ea545ec278940d840ed1-090d8826...

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...

Hello, I'm using dovecot 2.1.16 with SiS configured as: mail_attachment_dir = <mypath> mail_attachment_min_size = 128 k mail_attachment_fs = sis posix mail_attachment_hash = %{sha1} I'm having a few errors like: Sep 18 15:46:32 myotis51 dovecot: imap(igd): Error: Attachment file /mail/users/attachments/16/b0/16b0b2023a903db14d7f7bcdb1cc04c3f67a4fcb-b32c0a2aa6ae39527c870000a9061514 larger than expected (235866) They are really few and users haven't repo...

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't say anything about supporting variables. I'm assuming you can, otherwise all a...

...No such file or directory (FETCH for mailbox INBOX UID 42501) dovecot: imap(user at example.com): Disconnected: FETCH failed in=186 out=86389 My dovecot.conf attachment related config is: mail_attachment_dir = /home/%d/%n/attachments mail_attachment_min_size = 128k mail_attachment_fs = sis posix mail_attachment_hash = %{sha1} So, questions: - anyone else experiencing this? - how might this occurred? - what is the best way to find the corrupted message? - how should I go about fixing this? Any help or pointers would be appreciated. Thanks, Anand
