I've implemented the fundraising plugin and it's live now and taking donations. Thanks @cole and the others who helped develop this great tool. I've just tested again the donation setup and I'm using the Thank You Email option after donating, and the thank you email comes in from the servers email host. Something like email@example.com And this is a bit disturbing, as I feel donors shouldn't know this type of information and it should really just be sent from the email account associated with the paypal seller account (firstname.lastname@example.org for example).
I wanted to put that out there and see if perhaps I don't have it set up properly. I've look through my options pretty thoroughly though.
