= Email Validation =

This proposal is about adding an email validation facility to Trac.


== The Context ==
User enters a new or changes an existing email address in the general preferences tab. Under both circumstances, a verification email must be sent to the
user containing a link that will validate the email address to the system, so that the change will come into effect.

But the general preferences tab is not the only place where user's might enter an email address. Similar input fields exist in the ticket system where
one can add email addresses for ticket change notification. Other such notifications might exist, given the wide range of plugins making use of the
notification subsystem.

== Requirements ==
 ''WIP''

=== i18n requirements ===

The notification email clearly needs to be localized/translated.

== Consider Email Validation and Other Related Tickets ==

 * #8637
 * #9900

=== Discussion ===

While the proposal in #9900 can only be used for a quick validation of the user's input, it must also be extended to accommodate situations where
one has defined a default domain in trac.ini for sending the email messages to. In addition, the user must be send an email for verifying that it 
is both a valid email address and also owned by the user entering it.
