Updated the WP Mail SMTP plug-in to version 2.2.1. This is a minor update which fixes some bugs in stuff we don't use and adds a feature in Gmail in which we aren't interested. It modified 37 files and added 3, We have no local code in this plug-in. After syntax checking the changes, I made an update kit and applied it. Nothing appeared to break, and I was able to successfully send a test E-mail to myself. Several hours later, there have been no indications of problems, so I committed the WP Mail SMTP plug-in version 2.2.1 changes (Build 482) and published to GitHub.
