There are two ways to block email which is really Junk; that, somehow, gets through Google's SPAM filter. Here is the easy way. I'll post the harder way in a future post.
The drop dead easy way is to "tag" the particular email message as SPAM and hope that will pick up future messages and move them automatically into the Junk Mail folder. Sometimes that works, and sometimes not. There are two ways to do this: one in Apple Mail - the email client on the laptop and the other way is through the web interface located at GMail.com.
In Apple Mail, "Right Click" the email message and select "Mark --> As Junk Mail" from the pop-up context menu. This should identify all future messages from this sender/domain as Junk and never let it hit your inbox.

GMail offers you a few more "hardcore" options. You can actually report the email message as SPAM or a PHISHING attempt. This should not only mark the message as SPAM (or a phishing attempt), but also notify Google to watch out for these types of messages in the future.
