If you’re in the business of hosting WordPress-based sites or at least managing WordPress-based sites, then it’s likely that you’re also responsible for managing email accounts or how email is relayed from the site and the server to its visitors.
And depending on the nature of your setup, this may not be a problem; however, if you’re operating on some type of hosted solution, some type of managed hosting, or aren’t using a third-party solution such as Google Apps, then there’s a chance that site visitors are receiving emails from their favorite WordPress-based site with incorrect or unclear email sender information.
Case in point: I manage a site where comment notification emails were being sent with the following formation:
[ Site Name ] [My Email Address] via [Server Name ]
Obviously, this is okay if it’s my site, but a client’s site? Negative.
