I have left my Daily-Threshold setting at the default, which I understand to be 50 messages/day, a level of traffic for the list which I am comfortable with. However, on several occasions 50+ messages have made it into the daily digest (Wednesday's had 64). Is there another parameter (for example, the size of the messages) that determines whether the list is held? Thanks for any help.
