Okay, i need some further help. What i've tried with your hint:
Executing on cmd of director&proxy server: /usr/bin/doveadm -Dv -o mail_location=imapc: copy -u "dest_user_shard2" "dest_folder" user "source_user_shard1" mailbox "source_folder" ALL /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 I've also tried to execute "doveadm -c" with copied and modified configuration on director&proxy server without "'y' AS proxy" in sql password_query configuration part - without luck. This leads all to same debug output and result as command in first post. After that i changed to cmd of backend server of dest_user_shard2 and tried: /usr/bin/doveadm -Dv -o mail_location=imapc: -o imapc_host=<backend-shard1-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 [..] Aug 20 08:52:38 doveadm(source_user_shard1)<2442101><qAs8KVZtH2F1QyUA5QDIzw>: Debug: imapc(<backend-shard1-dns>:143): Authenticated successfully Aug 20 08:52:38 doveadm(source_user_shard1)<2442101><qAs8KVZtH2F1QyUA5QDIzw>: Debug: imapc: root=, index=, indexpvt=, control=, inbox=, alt= Aug 20 08:52:38 doveadm(source_user_shard1)<2442101><qAs8KVZtH2F1QyUA5QDIzw>: Debug: quota: quota_over_flag check: quota_over_script unset - skipping Aug 20 08:52:38 doveadm(dest_user_shard2): Debug: Mailbox dest_folder: Mailbox opened because: copy Aug 20 08:52:38 doveadm(dest_user_shard2): Debug: Mailbox source_folder: Mailbox opened because: copy Aug 20 08:52:38 doveadm(dest_user_shard2): Debug: Mailbox source_folder: UID 1: Opened mail because: copying Aug 20 08:52:38 doveadm(dest_user_shard2): Error: Copying message UID 1 from 'source_folder' failed: Mailbox doesn't exist: dest_folder (0.001 + 0.000 secs).

It is not what I expected and desired. So yeah i haven't get the whole picture right now. Maybe you can give me some details.

To do this kind of copying, you need to specify mail_location=imapc: and target to the director.

From my understanding doveadm has to look on 192.168.0.11 or 192.168.0.12 (according to provided configuration), but the > message says 192.168.0.21 which is backend for "dest_user_shard2". > > > > ----- Ursprüngliche Nachricht ----- > Von: Aki Tuomi aki.tu...@open-xchange.com > Gesendet: Freitag, 20.
