My network admin asked the following question when I asked him to let his email server accept messages for forwarding from my xwiki server: is your code secure? is there much chance that a malicious bot could harvest email and start injecting messages through your server? What should I tell him? Dan Svoboda Research Assistant Professor U Pitt Center for HIV Protein Interactions (412)648-7262 dsvoboda(a)structbio.pitt.edu
