AVG not recognising spam emails

Hi Gary,
If you mark that email as spam new similar email should be marked as spam automatically, not already received(evaluated) emails.
Thanks

We have AVG Internet Security 2014 installed with the Outlook plug-in.

We have been receiving lots of virtually identical spam emails recently. When I press the toolbar button to indicate it's spam the message is moved to the spam folder but subsequent messages that are the same, even from the same email address, don't get moved upon receipt. I have the sensitivity set to 51.

Am I doing something wrong?

Gary, Can you please provide AVG with a few of those emails to their FTP server (http://kb.avg.com/articles/How_to/How-to-upload-a-file-to-our-FTP-server) and score you have in settings of AntiSpam component?
