Hello!
I'm using 2 namespaces, "inbox" for INBOX and it's subfolders and "special" containing folders like Sent, Junk or Drafts. Though both use mdbox I decided to represent those namespaces in different locations "mdbox:~/mail" and "mdbox:~/mail_special_folders". The main reason to use 2 namespaces was to keep special_use folders out of INBOX by using the prefix attribute -- it's rather cosmetic.
├── INBOX
│ ├── SubFolder1
│ ├── SubFolder2
│ └── SubFolder3
├── Sent
├── Trash
├── Drafts
├── Junk
├── Templates
├── This is Ham
└── Report Spam
Now I want to export the emails of some former users to common known maildir or mbox format to be able to hand them over on CD. The problem is that a conversion with doveadm backup fails. I guess this is due to namespace special which is configured with a manual location attribute instead of utilising mail_location. But even telling doveadm to backup only one namespace leads to the identical error (extract of debug message at bottom).
As this is a RHEL7 server, the dovecot version is an old 2.2.10 and I don't expect software debugging -- I just ask if I did some misconfiguration or a failure in the command.
I already thought of merging the locations of both namespaces. Yet, I'm not sure how to achieve this.
From /etc/dovecot/conf.d/10-mail.conf
mail_location = mdbox:~/mail
namespace inbox {
type = private
hidden = no
ignore_on_failure = no
inbox = yes
list = yes
location =
prefix = INBOX/
separator = /
subscriptions = yes
}
namespace special {
type = private
hidden = no
ignore_on_failure = no
inbox = no
list = yes
location = mdbox:~/mail_special_folders
prefix =
separator = /
subscriptions = yes
}
HOME is set by LDAP
user_attrs = =home=/srv/mail/%Ld/%Ln,=uid=20000,=gid=20000,imapQuota=quota_rule=*:storage=%$G
