Assistance with doveadm backup...

[SH Development]

Here is my command:

[root at mail maelstrombackups] #mkdir -p vmailbackup
[root at mail vmail]# chown: vmail:vmail /mnt/maelstrombackups/vmailbackup
[root at mail vmail]# doveadm backup -u jeff maildir:/mnt/maelstrombackups/vmailbackup

Only gives me the usage list, doesn’t work.
