Increasing the threshold has multiple POSSIBLE implications:
1) e-mail loops take longer to stop
2) more list traffic when you might not want a
chatty list i.e., user needs to "process" --
read, file, discard, act on
3) more host processing during prime-time for a list
that maybe should not use alot of prime-time CPU
4) more space dedicated to archives
5) more bounces to handle (by owner/postmaster)
6) more bandwidth used (somewhere)
NB: please note the use of the word POSSIBLE. Your
mileage can and will vary.
