similar to: maildir vs dbox?

I'm facing some issues on mdbox based backups. Backups are failing with dbox corruption messages. SiS is the greatest advantage though. However backups integrity is very important. If SiS/Deduplication is not a requirement stick to Maildir.

Hello Dovecoters, I am using dovecot-2.2.10-8.el7.x86_64 on RHEL 7.4 When I backup mdboxes (using SIS) using this command doveadm -Dv -o plugin/quota= sync -1f -u user1 at user.com mdbox:/mailbackup/user1 mails get backedup but all m files are not copied. Last file copied is m.4 If I run the command again I get below error I tried with doveadm backup command as well (many times).

Hello Actually we use MBOX format for all our IMAP access but users complain they cannot create subfolders in imap folders, of course they cannot because of MBOX format ... I need gurus advices on changing mailbox format Maildir of Dbox ? What would be the safest way to go ? Note : we extensively use Thunderbird here. Thanks

Hello, I've got a Dovecot 2.3.x setup. Currently it's running Maildir storage. I'd like to convert that to Dbox specifically Sdbox safely. I'm also looking to at the same time or shortly thereafter encrypt the email storage with mail_crypt. Any help appreciated. Thanks. Dave.

I am interested in finding out your experiences with using the dbox format (especially mdbox) if you use this format. I am contemplating changing my maildir setup to mdbox but I still need to make a case for it against maildir which has become a de-facto standard and provides sort of a secure basis in case of software changes. Your input will be appreciated. -- Andreas Kasenides Senior IT

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

Just a note to myself and whoever else cares, should be added to wiki once it has its own page about this: With single-dbox messages can be copied with hard linking. This means that there can be multiple files that point to the same attachment file. The attachment is now deleted only once the mail file's link count drops to zero, so this works fine.. ..until someone goes and starts manually

Hello, Thanks. Are there any performance or stability advantages Sdbox over Maildir? I'm also thinking ease of encryption an Sdbox or Mdbox vs Maildir? Thanks. Dave.

One reason why I migrated a few sites is that when reporting issues with maildir on this list, there seems to be lack of interest in fixing them. In that regard, it can be seen as a safer choice.

Hi, How do i convert from Maildir to dbox using the convert plugin? My users reside in /home/user/Maildir. In the dovecot.conf file i've set up convert_mail = dbox:%h but I am not sure about the syntax. Im getting the error: Couldn't create mailbox directory INBOX Mailbox conversion failed, exiting Thanks -- Kjartan

Now that v2.0.0 is only waiting for people to report bugs (and me to figure out how to fix them), I've finally had time to start doing what I actually came here (Portugal Telecom/SAPO) to do. :) The idea is to have dbox and mdbox support saving attachments (or MIME parts in general) to separate files, which with some magic gives a possibility to do single instance attachment storage.

Ok... Now that I've got the niggling issues resolved, on to bigger and better things. I want to convert everyone from Maildir to dbox and enable SIS (our users use a lot of large attachments), and after some reading/googling, I think it may be better to use dsync instead of rsync for the actual migration after all since it will do this at the same time as the syncing. If I'm not

Hello, If anyone has autoconfiguration going with their email domain please email me privately. I'd like to ask you some questions about your setup. What do you use? Thanks. Dave.

Hello, Thank you, yes I have, it's not answering my questions. Thanks. Dave. On 5/28/19, Ralph Seichter via dovecot <dovecot at dovecot.org> wrote: > * David Mehler: > >> Are there any performance or stability advantages Sdbox over Maildir? > > Have you read the documentation at all? > > -Ralph >

I am migrating our mail server from Courier-IMAP to Dovecot. We currently use maildir storage format. What are the advantages and disadvantages of Dovecot's dbox format over maildir? Does anyone have any performance benchmarks for both? What do people use to test performance? We are running on a Mac OS X box (10.5.7) using Postfix 2.6. Thanks, James.

Hi to all, my question is: Is possible implementing SIS (with hardlink) with maildir instead of *dbox format? If yes in dovecot.conf it's only necessary the below parameters or what else? mail_attachment_dir = /var/qmail/attachments I have also acting the zlib plugin it is not a problem isn't it?

Hello, i use doevecot 2.2.18 current. My Problem is with email-extension and case sensitiv folders. Example: user+extenstion will be delivered to the user and subfolder extenstion so this is okay. but user+extenstion will not be delivert to the user and exiting subfolder Extenstion so that is not okay. The mail will be also delivered in the subfolder extension. The exiting Folder Extension will
