have transferred the maildir for a couple of users to a new VM, created same set of users and assigned the below permissions to their respective Maildir folder:
chmod –R 700
chown -hR user:user Maildir
However when testing incoming emails to any of these users it seems that somehow root is trying to create some folder/file and email bounces back due to lack of permission:
Sounds like permissions issue but not sure which and where is the issue and why it is trying to write to: /root/Maildir/tmp/ instead of the actual user Maildir directory.status=bounced (maildir delivery failed: create maildir file /root/Maildir/tmp/1422603535.P2982.mail.domain.com: Permission denied)
Thanks
