<p style="font-family: arial,helvetica,sans-serif;margin-bottom: 0; margin-top:0;">Hi,<br />
<br />
i want to copy e-mails from user "source_user_shard1" and folder "source_folder" lying on backend servers (shard1) to another<br />
user "dest_user_shard2" and folder "dest_folder" lying on different backend servers (shard2) via command line tool doveadm copy<br />
executed on dovecot proxy&director servers. But doveadm seems to look only on "dest_user_shard2"'s backend for folder "source_folder"<br />
of user "source_user_shard1" and can not find it. To confirm this, i've checked directories on filesystem on backend of "dest_user_shard2"<br />
and a folder for "source_user_shard1" was created including one folder "mdbox" and only one file "dovecot.list.index.log" in it. Folder and file<br />
timestamps match the command debug output time.<br />
"doveadm list" executed for both users show the right folders (source_folder and dest_folder exist in respective mailbox).<br />
<br />
Is it a bug or wrong usage of tool? Please advice.<br />
<br />
command executed on dovecot proxy&director server with debug output:<br />
/usr/bin/doveadm -Dv copy -u "dest_user_shard2" "dest_folder" user "source_user_shard1" mailbox "source_folder" ALL<br />
