Modified the way backups are created to eliminate problems with hard links. NOTE: This change involves the archiving of user's running as the user themselves, not as root. This means that any files that the account's user cannot read will NOT be backed up.
Made the backup.pex script fall back to a default temporary working directory if an invalid directory is specified with --tmp-dir parameter
Fixed a problem with temporary backup storage counting towards user quota and causing failures
Released updated maildrop RPM with improved default permissions
