Change no-reply emails to use vanity URLs

Could we change the no-reply emails to use vanity URLs instead?

Rather than have no-reply@ihubapp.org or no-reply+digest@ihubapp.org, instead use no-reply@projectrollplay.ca or no-reply+digest@hubifynow.com.

Some potential clients place emphasis on product branding and have to have every look as though it is coming from them.
