I had to install WP-Mail-Bank in one of my WordPress pages/blogs/store, so it can send emails to *people* 🙂

I was getting “SMTP Error: Could not authenticate”  on the test email tab.

I had to went to https://accounts.google.com/b/0/DisplayUnlockCaptcha and continue with this request. This gives us a 10min window to connect to Google in an *unsecure* way. Google detects the connection and allow it for the future.
