Based upon previous readings of LSTOWN-L and the docs, this list option
does NOT prevent text attachments from being distributed.  I believe the
.VBS is basically a scripting language written in "plain" text, not encoded.

SIZELIM= value.  The included text was over 300 lines.  I have my list
set to 200.
