=v= I handle a similar situation like this: do a directory-wide operation, then record the directory's modification date. Next time around, check the directory's modification date and skip the operation if it hasn't changed. In this situation, that way you would know that the last message hasn't changed since the previous operation, so you can skip the directory read. <_Jym_>
