Email Plugin - working?

Hi folks, Wondering if anyone has had the opportunity to use the email plugin at all on B2 or B3? Specifically, I have two things I'm trying to acchieve: 1) Setup email notifications for changes to specific parts of a document (eg, change occurred to field x in document y). Can't seem to find anything specific for details on this,- if there is something there, please point me in the right direction. 2) Emailing from the Xwiki system directly (documentation/faq for which seems to have disappeared since I last used it to implement on 0.9.840). The origional sample which Ludovic wrote up is still there (http://old.xwiki.org/xwiki/bin/view/Demo/SendMail on the old xwiki site), but configuration documentation seems to be missing, From recollection, there was a few things we had to configure - as the default HELO is sent using a combination of fields which includes the version number (and naturally gets rejected by our SMTP server as it is not a valid email address supplied as origionator).
