Usually YA issues this message when your e-mail account may have been hijacked and used for spamming. To find the spamming source and to make sure that it isn't you causing this, Yahoo has to temporarily shut down your mail account. During the suspension, you have access to all email in your inbox, personal folders and sent folder, and to your mail options. You will not be able to send or receive mail or save any drafts. Email sent to your account will bounce back to the sender.

Other probable causes

#1: Somebody may have tried to enter your account without being authorized, and he may have tried to do so a couple of times. After a couple of failed attempts to open your mail account, Yahoo also temporarily shuts it down for security measures. In some cases a user may not even try to get into your account, but he may want to cause trouble for you - he just knows that after a couple of seemingly unauthorized attempts to enter your account, Yahoo shuts it down for a couple of days. Often an automated program is used for this which can send more than 1000 requests a minute. The Yahoo servers detect that a human can't be behind such attempts and presto, the account is shut down.

What you can do is go to: http://login.yahoo.com/config/login . After your first try you'll probably get a failure message, but when you try again, you'll see a captcha link. Only real life people could handle this correctly, spambots can't read it. If you are lucky, you may be able to enter your account at this point.

#2: If you send large amounts of mail, even if it is for non-profit organizations, Yahoo may close your account temporarely because their program can't tell the difference between a supposed spammer and a real one.

Summary: if the login hack doesn't work, wait a little, a suspension usually lasts about 48 hrs. If you then still can't get in, go to this online help form and describe your problem:
