Hello everyone,

 

1. I was wondering whether mail-crypt is intended to be supported in the long run.

 

2. Furthermore, I was wondering about the best way to backup a whole email server with mail-crypt enabled.

 

(3. how do i use dsync with mail-crypt?)

 

Below are my thoughts so far. 

 

- doveadm seems to work on each user individually, and it seems that the password is required for this? At least tachtler/dovecot-backup complains about missing the key and password to decrypt the mails, and so does "dsync -f -u a@bc.de backup maildir:bc.de/a"

 

- I was going to just tar /var/mail, but it appears that maildirlock is deprecated and broken, so I would have to shut down dovecot temporarily, in order to maintain file/index integrity, which is not ideal.

 

- Running it in some kind of virtualized environment to be able to take atomic snapshots might work, but I read that the "uuid list", or whatever, is only updated "lazily". Would a shutdown even solve that?

 

- I just saw that replication is going away. Maybe it would not have supported mail-crypt anyway.

 

Thanks for any input.
