FYI, one thing a future mail-rearchitecture might consider supporting:
A better way of querying whether SMTP is working and the registration email
address is valid prior to creating the user being registered. It would
probably be a good idea to add the user and the user-document only after
successful SMTP delivery of the registration message. Or cleanup the created
user/document in a catch() on SMTP failure in
com.xpn.xwiki.XWiki.sendMessage().
Note bugs in current feedback and UI-flow on registration email errors:
http://jira.xwiki.org/jira/browse/XWIKI-3492
Two problems that arise when following options enabed:
- Administration->Registration->Use email verification == yes
- Administration->Registration->Check Active fields for user
authentication==yes
(1) /xwiki/bin/register/XWiki/Register allows registration of a user with
an empty email field.
After submission, a "dead" user is created with the name given by the user.
That account will of course never be automatically validated given that no
email went out. The user gets to figure out what's wrong by reading the
stacktrace resulting from hitting "submit" with an empty email field:
A problem occured while trying to process your request. Please contact the
webmaster if this happens again.

(2) /xwiki/bin/register/XWiki/Register allows registration of a user with a
bad or bogus email name, resulting in another backtrace:

In both cases, the creation of a XWiki.username document and associated
XWiki.XWikiAllGroup entry shoudn't occur until after successful send of the
registration email. Also, some common validation rules for email fields
should be applied to the registration page's email field when "Use email
verification==yes" && "Check Active fields for user
authentication==yes".
