Email from server

Hi folks, Currently trying to setup email sending for our xwiki server, and following the outline provided at (http://www.xwiki.org/xwiki/bin/view/Demo/SendMail3); but does not seem to be functioning correctly for me. On my end, the xwiki server just goes into an endless loop (like as though it's trying to access a large chunk of data). Has anyone set this up on their own local wiki server, and if so are there any guideline configurations?
