[xwiki-users] SMTP authentications

Hi, I have crawled the mailing lists and support forums on this but I am unable to figure out the answer. I am evaluating Xwiki and love Workspaces from what I've seen so far. The one thing that really bogs me down is the inability to register an authenticated SMTP server. I have read there is a patch from Liliane, and the feature is included on 1.6 but I just can't seem to understand how to get is to work. In an evaluation perspective (and very much so as well in production), not being able to use authenticated SMTP server is a no go for me. Could you please point me to a resource that clarifies what the situation is and possibly, the steps to enable it on 1.7. Thanks ! norguir
