IMHO, the biggest problem with a low limit is your membership will see
black-out times (when the list is held) and worry.  When they post, but
don't see their article appear, then worry.  When your membership
worries, the list owner will have (otherwise unnecessary) work to do.
 
On the other hand, you should get it very clear in your mind why you are
setting a limit and what the effects will be.  Are you trying to
stave-off a mail-bouncing war that will fill everyone's mail boxes with
junk mail?  (not likely with LISTSERV: thanks, Eric!).  Do you have a
member or two that dominate the list with many postings a day (that you
don't want)?  ("Daily-Threshhold" probably won't help save the list).
Do you want to slow down discussions when a particularly interesting or
caustic topic comes up?
 
Ten mail files a day *is* a lot for some folks.  And maybe those folks
are especially valuable to your list.  Give them the capability of
subscribing with DIGESTS ...  it doesn't cost a thing, assuming your
LISTSERV is up-to-date.  Mention to them the possibility of local or
global redistributions such as NETNEWS/Usenet ...  their site may have
it available.
