Well, it depends on the list.  If you allow attachments, you may have to
moderate/preview all postings to the list.  I allow only text on my lists,
anything with an attachment is automatically rejected, regardless of whom
it comes from.  In my list headers:

* Sizelim= 200         (that's 200 lines, including header)
* Attachments= NO
* Language= NOHTML

Have problems with viruses/worms other ways, but they never get distributed
to the subscribers to my lists *via* my lists; they don't get past those
header settings.
