Incorrect permissions for /var/qmail/mailnames/ directory. It should be as follows:

# stat /var/qmail/mailnames/ | grep Access
Access: (0700/drwx------)  Uid: (   30/ popuser)   Gid: (   31/ popuser)
Access: 2015-12-23 16:59:20.527983735 +0700


Correct the permissions as below:

# chown -R popuser:popuser /var/qmail/mailnames/

Make sure /var/qmail/mailnames/domain.tld/applications/Maildir/ has the same permissions
