How can I block certain email addresses in Yahoo?

if you click on options (far top right of your mail page) then click spam in the list in the left panel,the second part of the page is for adding addresses you want blocked from arriving to you

On the mail screen click Options, then click Mail Options. On the list to the left click Spam. Enter the email address in the block, click Add Block. Upper left click Save Changes. They will not get a notice of the block, it will not be returned to them, it will be deleted upon arrival at your account.

You can also check the box on the Spam site for the email you do want.

If you get mail you want in your 'spam' folder, then you go into the 'spam' folder and open the item you wish to keep. Click on the 'Not spam' button and it will be returned to your in box, also allowing that address to be delivered to the in box from now on. However, go in periodically and check to insure all items are spam.

Also, make sure that address is in your address book, as it helps to ensure that address as a "safe" one.

Now, I must warn you, if you get another E-mail that has the look of spam again, it will once more be redirected to the spam folder, and you will have to do this all over again.

You can not completely stop all spam, but you can help to put a big dent in it.

First, try not to open any of them, that only makes them send more and more to you.

Check mark them and click on 'Spam,' this should stop those addresses from being delivered to your inbox.

Use your spam guard and block address.

Look for the 'Options' link at upper right corner of mail screen and click on it

Options /mail options

Click on 'spam' in the list on the left.

Make sure spam guard is on, by checking in the little box.

Then in 'Blocked Email Addresses,' enter the E-mail address you wish blocked, in the box after 'Add a blocked address' and click on the 'add' button, then click on save changes at top left of screen.

You will never get mail from that address again.

This should help you to control your spam.

Other tips:

Do not ever open E-mail from people you do not know; and unless you are absolutely sure who it is from then treat them as spam.

Opening spam alerts the sender that your address is a valid one and they send you loads and loads more of it to you.

Never, ever give out your account information or other personal information to anyone.

If you are on a site and you absolutely have to sign up for something, check the entire page to make sure you uncheck any lines wanting to send you any other info, notices, catalogs, ads, and the like.

Added detail:

Yes, spammers change one item in their addresses a lot, so you might try blocking the entire domain, by putting in

*@ thedomainyouwanttoblock.com

for instance: *@seeyou.com

Or, if they change the domain, instead of the company name you can block the name by putting in Imatheft_inc@*

Hope this helps
