How do I change the description of the email address for RSVP messages?

So, i've set up my event and all is working fine. The RSVP confirmation email message comes from the right email address I set up (training@smartchangesolutions.com), but the description of the email address is 'WordPress' (WordPress<training@smartchangesolutions.com>.

The issue is that when the message comes into a client email inbox, the 'From' column will show 'WordPress' only, not 'Training@smartchangesolutions.com' and I'm afraid the user will not recognize it, get confused, ignore it, or the mail client will send it to the junk folder automatically.

In any case, I'd like the description to be different, even if only for branding purposes but I can't find anywhere in the admin options where I can change the description. Is this possible? How?
