use sent email feature without user email

Closing as lack of interest from community.

Thanks Mr

1. I'm not yet family with this kind of stuff. Thanks for your comment, now i get more confidence to use it .
2. I don't know about other guys will receive email when a key get from center server. your comment push me to come back
3,4 this is my quick patch, i need it soon, so don't have enough time to self check. that why i don't switch issue to peer review.

your comment is great to push a wiki like a contribute guideline, i will do it when i refine patch.

Thanks , a peer review of the patch:

• the migration script has ConfigurationLevel=S, but the code is using MSysConfig with AD_Client_ID. For these cases the ConfigurationLevel must be set to Client, so, it has a System default, but it can be overwritten in any client

• when generating migration script is good practice to set the comment in DICTIONARY_ID_COMMENTS sysconfig key. The migration script will receive it, but also will help to let know other developers what's the reservation about when receiving the email

• Is advised to regenerate serialVersionUID when adding public methods to model classes

• For this specific ticket, overwriting the getEMail on MUser sounds beyond the needs of the ticket. I mean MUser.getEMail is widely used in many other points (and probably external unknown plugins). I think is better to restrict the scope of the change to the point where is required for this ticket.
