Notes

I have checked your issue and I need to let you know that our team is already aware of the spam emails and the team is already working in it. The challenge is blocking mail server IP addresses. The spammers are resorting to using different mail server IP addresses every time to send out the spam message. The ones that hit our folders are blocked and you will not see any email originating from that mail server IP address.
Keep on reporting these out to us so that we can block new mail server IP addresses originating from those domains.

There are 2 things that you can do in Web Mail. One is to search for all the emails and mark it as spam and Second is to add .us in Blocked Senders Lists.
To search for the emails in Web Mail, login to Web Mail > Click on Search Mail option > In the Search box, type aolea.us > In Headers, check on From and uncheck other options > In Folders, select Inbox and click on Search. Then, place a check mark next to Sender Column at the top of first email to Select All spam emails and click on Spam button.
This will mark all emails as spam at once for you. It will help us to find out the different mail server IP addresses the spammer would have used to send out those spam emails and get it blocked.
To add the domain .us in blocked senders lists, please sign in to Web Mail > Click on Preferences > Click on Address Book tab next to Sending and Replying tab in Web Mail > Click on Edit Blocked Senders. Type the domain as .us and click on Block this domain and click on Save.
