Hello,
Sorry for the reply delay, I had to worry about something else …
Here is my *doveconf -n*:
# 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf
# Pigeonhole version 0.5.4 ()
# OS: Linux 4.19.0-6-amd64 x86_64 Debian 10.4
# Hostname: /[my-host-name]/
auth_debug = yes
auth_debug_passwords = yes
auth_verbose = yes
auth_verbose_passwords = yes
imapc_features = rfc822.size fetch-headers
imapc_host = /[remote-imap-host]/
imapc_password = # hidden, use -P to show it
imapc_user = /[my-remote-user-name]/@/[with-domain]/
log_path = /var/log/dovecot.log
mail_debug = yes
mail_location = mbox:~/mail:INBOX=/var/mail/%u
mail_prefetch_count = 20
mail_privileged_group = mail
namespace compat1 {
alias_for =
hidden = yes
list = no
location =
prefix = mail/
separator = /
}
namespace compat2 {
alias_for =
hidden = yes
list = no
location =
prefix = Mail/
separator = /
}
namespace inbox {
inbox = yes
location =
mailbox "&AMk-l&AOk-ments envoy&AOk-s" {
special_use = \Sent
}
mailbox "&AMk-l&AOk-ments supprim&AOk-s" {
special_use = \Trash
}
mailbox Brouillons {
special_use = \Drafts
}
mailbox "Courrier ind&AOk-sirable" {
special_use = \Junk
}
prefix =
}
passdb {
driver = pam
}
passdb {
args = scheme=MD5-CRYPT username_format=%u /etc/dovecot/users
driver = passwd-file
}
plugin {
sieve = file:~/sieve;active=~/.dovecot.sieve
}
ssl_ca = </etc/letsencrypt/live/default/chain.pem
ssl_cert = </etc/letsencrypt/live/default/cert.pem
ssl_dh = # hidden, use -P to show it
ssl_key = # hidden, use -P to show it
userdb {
driver = passwd
}
userdb {
args = username_format=%u /etc/dovecot/users
driver = passwd-file
}
There is certainly something trivial there, but I'm not very used to
advanced usage of Dovecot.

Gingko

Hello,
I also have issues using Dovecot Backup.
I am trying to Backup (or possibly Sync - one way) a single user IMAP
account from a remote server, unknown type, to my own server.
For that purpose, I defined the following parameters :
imapc_host = <host name>
imapc_user =<user name>
imapc_password = <password>
imapc_features = rfc822.size
(<user name> has format: n...@example.com <mailto:n...@example.com>,
and <host name> is the name of the imap remote server that I use for
getting mails)
… and then I issued the following command:
doveadm backup -R -u <user name, formatn...@example.com
<mailto:n...@example.com>> imapc:
... but doing this, I get the following answer:
dsync(<user name>): Info: imapc(<host name>:143): Connected to <host
IP address>:143 (local 192.168.1.2:52940)
dsync(<user name>): Error: Failed to initialize user: namespace
configuration error: Namespace mail/ can't have alias_for= to a
different storage (different root dirs)
How can I solve this?
If there is something not matching between servers, I may eventually
change configuration on my side, but I think I would first have to
know which feature(s) I have to know from the remote server in order
to create the matching one on my server.
Is there a way to list all relevant data coming from the remote server?
Also:
Doing this, is it necessary that the source user name be the same as
the destination user name? Is it possible to backup an IMAP account
to a user account having a completely different name?
Nope. Source and destination usernames can be different. Please post
your doveconf -n as this is probably an error on your local config.
