How do I stop a spammer who changes his address everyday?

Moscode: How do I stop a spammer who changes his address everyday?
Someone sends me stock tips daily. When I mark the mail as
spam I get a new stock tip from a new address. So just marking it spam does not help. Any suggestions on how to stop this?

Get a new email address. Either that or call your email company.

Depending on your service, you may be able to allow only emails that you pre-approve.

I get those too. I feel your pain!

It only happens with certain ISPs, and has a lot to do with certain websites who ask you to regester, then sell your details. Never go for the free ipod scams, they just want to put you on a database.

Get gmail or hotmail, and maybe macafee site tester. Don’t give your email address out again. Report spam as it occurs. Some ISPs will help, some won’t.

I’ll be watching this question for more answers, as I really could do with help with this too!

Put stock Tips in a filter. Send the filter to be delivered to the Trash. Here`s how. = Yahoo! Mail offers two ways to help you block unwanted messages:

If you receive multiple messages from the same source and would like to block the sender, you can set up a filter to match some unique part of the sender’s address. Generally a name or a phrase in the body of the message works well, but as long as the sender always uses the same mailing address, filtering based on the From: field is very effective. Just set the destination folder to trash.
Note that using filters like this to avoid unwanted mail doesn’t actually stop it from being sent.

For further information on how to create a filter, please see: How do I create a filter?.

You can also use the “Block Address” link. If you receive a message from a sender and want to block that sender, please follow the directions below:

From your inbox, check the box next to the message
Click the “Spam” button at the top of the page
The message will be marked as spam and the sender’s email address will be added to your Block List.
If this option is not working, please ensure you have enabled this feature in your Spam Protection settings.

To check the settings, click on “Mail Options” and then on “Spam Protection.” On the Spam Protection page, please make sure “Add the sender’s email address to my blocked addresses list” is checked and then click on the “Save Changes” button.

It’s easier for you to spam his/her adress than it is to him/her to create a new account. Soon enough he will get tired sincde there is no point of doing it.
