@sinisterspatula Probably, yes.

The thing is, we don't interface with MongoDB directly. We use an abstraction layer, and so if your database of choice supports all of the commands we throw at it (you can see the abstraction layer methods in src/database/*), then NodeBB can theoretically support it.

Final update, it worked on the production server!! so now our forum is working properly sending emails the Linux way on a Windows Server OS, quite nice I would say, just as a side note our forum is actually really small in number of users, as it is an internal forum, so I can't assure this setup will work out to other forum's expectations or needs, also I would like to add that this shouldn't be the way to do it on Windows as it is kind of a weird way to handle it so in later versions it would be nice to see it reworked or polished for Windows environments (especially because it looks like the program used to simulate sendmail on Windows is no longer receiving maintenance).
