Project Donation Email Response Sender Name

I just finished going live and doing a few test donations. When I received an email acknowledging my donation, the sender name showed up in the email as “WordPress.”

I would like to have it come from some other name I create, like the key word of the project site – 6058 Donate so as to be more relative and non-generic.

I can’t for the life of me find any settings anywhere that determines what this should be, unless it is some default code in the appearance editor interface.
