This is subject to correction by those more knowledgeable, but, if your
subscribers want to switch from DIGEST to MAIL (individual messages) they
send set corgi-l mail .  If they have digest already set and want to
suspend list mail for a little while they can send either a set nodigest
or a set nomail, doesn't matter which they use.  But, when they return, if
they want to resume digests, they must send a set digest.  If they used
set nomail and think set mail will cause the digests to resume they'll be
surprised; they'll get the list mail but not the way they want it.
 
Nodigest stops delivery of mail, like nomail does.  To change the format
of the delivery it must be done explictly (and someone who had digests but
set the sub nodigest and then sets it mail, thinking the digests will
resume, is making an explicit delivery format change, and will not get the
digests).
