It's a sort of a game.  You have to decide what the largest message you
want to go through the list is and set Sizelim= accordingly.  If someone
then posts a message with an attachment that is longer than Sizelim=,
then LISTSERV will reject it.  Otherwise LISTSERV will accept it.  There
is no way to specifically reject attachments other than by overall message
size.  I generally set Sizelim= 400 or less on most of my lists for this
reason.

==================

In real terms... decide how big you want the limit to be in terms of how
many KBytes. For each 100k of attached file, roughly 1800 lines of MIME
(B64) encoding are required (+ a few for overheads). So, for example,
setting a sizelim=400 would allow for attachments up to about 25K.
