I'm not David, but I just read the entire page and one thing that I was
specifically interested in has to do with the importance of the index files.

I seem to recall reading somewhere that dovecot saves more than one
version of the index files to reduce the chance of losing the indexes,
but I don't see anything about that.

Also - is it possible to configure dovecot to keep multiple copies?

I was also planning on putting the indexes on either a ZFS or BTRFS
partition to further reduce the chance of data loss (self-healing
preventing silent data corruption, and snapshots), but only saw a
comment that they can be stored in a different location, but nothing
about why you might want to do that - e.g., to use a more resilient
filesystem to store these critical files.

Another aspect I'd like to see is recommendations for backup strategies,
with respect to the fact that the indexes are so critical.

David, in particular, is there some question you feel that the wiki

Are you sure you read it? https://wiki2.dovecot.org/MailboxFormat/dbox seems

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.

Convert Maildir to Dbox?

2019-05-28 Thread David Mehler via dovecot
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.
