Ok, so is it possible to change the timeout value or change the number = of dns queries retries, even if 'out of dns standard retry policy rule', = as because some dns servers don't accept tcp connexions, and many packets = are lost due to qos policies at isp side and slow or busy lines, some xmail admins should really have to delay the ultimate 'A record attempts' to = have chances to get really existing mx records ?
