To have the digest sent when it reaches a certain size, enter the minimum number of lines into the
Max digest size before sending field. Selecting
Unlimited tells Majordomo to ignore the size when deciding when to send the digest.
It is actually possible to enter values for both the
Oldest message age and
Max digest size fields. If so, it will be sent as soon as either condition is met. You can set both fields to
Unlimited instead, but this means that the digest will never be sent!
