• Can't send emails
• Received "suspicious activity" error

To protect from possible abuse, Yahoo!7 Mail can temporarily suspend a user from sending messages if we detect suspicious activity in an account. During the suspension, you can’t send email, but you can receive messages and access to email in your inbox and other personal folders.

If your account has been suspended from sending messages, we recommend you wait a few minutes before resending your message.

To avoid receiving this error in the future:

• Avoid sending messages to a large number of recipients. Instead, send the message to smaller batches of recipients. (If you frequently send mail to the same, large group of people, we recommend you use Yahoo!7 Groups, which is better equipped to handle large email lists.)
• Avoid sending a large number of emails in a short time period.
• In your email messages, avoid using phrases that our system might interpret as spam.
• If you suspect that someone else is using your account to send messages, change your password immediately.

If you still can’t send email 48 hours after receiving the error message, please contact us.
