AW: Problem with copy e-mails via doveadm

Fri Aug 20 13:39:19 EEST 2021

Please explain in more detail how I can do this.

> Try targeting your director instead.
in cmd of director
 /usr/bin/doveadm -Dv -o mail_location=imapc: -o imapc_host=<director-dns> -o imapc_user="source_user_shard1" -o imapc_password="source_user_shard1_password" copy -u "dest_user_shard2" "dest_folder" user "source_user_shard1" mailbox "source_folder" ALL
does no change, like i said.

in cmd of backend shard2
/usr/bin/doveadm -Dv -o mail_location=imapc: -o imapc_host=<director-dns> -o imapc_user="source_user_shard1" -o imapc_password="source_user_shard1_password" copy -u "dest_user_shard2" "dest_folder" user "source_user_shard1" mailbox "source_folder" ALL
results in same output than targeting backend shard1 direct.

> The problem actually is that you are now targeting the source user into the source user as well. You need to, somehow, make dovecot return mail=imapc: for the target user. Or you can try to do the copying on the target backend instead, so that you can return `mail=whatever your mail location is` from userdb lookup easier.

mysql dovecot configuration part:
user_query = SELECT '/vmail/%Ld/%Ln' AS home, 10000 AS uid, 10000 AS gid FROM users WHERE email = '%Lu'
password_query = SELECT email AS user, password, 10000 AS userdb_uid, 10000 AS userdb_gid, '/vmail/%Ld/%Ln' AS userdb_home FROM users WHERE email = '%Lu' AND active = '1'

Isn't my described attempt on backend of dest_user_shard2 exactly what you described as possible next try? If not what has to be changed?

The problem actually is that you are now targeting the source user into the
source user as well. You need to, somehow, make dovecot return mail=imapc:
for the target user. Or you can try to do the copying on the target backend
instead, so that you can return `mail=whatever your mail location is` from
userdb lookup easier.
