I changed the sender email to be a real mailbox instead of noreply@
The goal is to catch the bounces and clean up our user database.
It is a start towards https://dev.tiki.org/item3756-Manage-email-bounces
An improvement: the from name will indicate which site sent the email, and the email will be common for all sites. This will provide more flexibility for filters.
I will do the other *.tiki.org sites later.
Feedback or suggestions?
