I can't wait for this to be officially released. Anyway on to the main question:
Will there an option for all forum-generated mail to be sent through an authenticated SMTP server, like how vB has it? If it's already implemented GREAT! If not, maybe it can be considered for the first release?
Although some forums may not have a need, other forums (that I have been around, mine included) would need to use an SMTP server for outbound mails for ensured delivery instead of directly spitting them out of the server's local mail system
