With the great help of Michael Bartlett I've configured both the Discuss@
and Workgroup@ lists so that only a specific type of attachments can get
through. If an attachment doesn't match a specific mime type it will not be
allowed onto the list.
image, office apps, pdf, flash are still allowed through.
PIF, ZIP, and EXE are NOT allowed through (e.g.)
For the most part people shouldn't be sending attachments at all through
this list of any type ... but there might be cases where it is necessary and
I don't want to eliminate it at all. Also, I definitely want to keep
allowing HTML e-mail (multi-part). The suggestion for posting stuff that
might ordinarily be an attachment would be to put it on a URL where you can
direct people to.
Thank you and I hope this will eliviate people's fears about viruses.
