Take the 2-minute tour ×  Is there a security configuration in
WSS 3 that would allow end-users to add documents to a site, but
then not be able to change this document?  share|improve this
question add comment  1 Answer  Are you able to configure
document lists to accept email messages with attachments? If so,
then you could configure your list to accept messages from any
address while granting read-only access.  This is easy to do
with Microsoft Office Sharepoint Server, and that's built on top
of WSS 3.  share|improve this answer add comment  Your Answer
