This patch adds the ability for the system to check an
email address entered by a user (either at registration
or when editing a profile) against the smtp host
provided in the address, to see if teh host thinks it
is a valid email address.
This functionality is to stop malicious users entering
false email addresses, particularly once registered and
is considered a good preventative step against spammers
and the like.
The attached zip file contains a diff file and three
new files that need to be added under the class directory.
