This tried to write to /root for some reason and failed (dovecot

2.1.3):

# time doveadm -o mail=maildir:/home/bu/test.mdbox import maildir:/home/users/user@domain.com/Maildir "" all doveadm(root): Error: chdir(/root/) failed: Permission denied (euid=10025(vmail) egid=10025(vmail) missing +x perm: /root, we're not in group 0(root), dir owned by 0:0 mode=0550) doveadm(root): Error: chdir(/root) failed: Permission denied doveadm(root): Error: Can't find namespace for mailbox Trash doveadm(root): Error: Can't find namespace for mailbox test

Or if it's the mail reading code:

time doveadm fetch -u user@domain text all > /dev/null

This ran quicker than a full dsync. Only 40s for 3.1GB. rsync still

beat it clocking in at 16s. I ran the fetch command twice figuring the files would get cached by the OS.
