Yet another glitch on only some of Yahoo's servers? It's been happening for the last couple of days.
'Suspicious activity' means that Yahoo suspects you of spamming.
1.Although the limit for the number of addresses in a mail is 100, frequently your mail is frozen with far fewer. Try sending mails with shorter lists of addresses, and of course use BCC for privacy, sending the mail To: Yourself.
2. There are also limits on the number of mails sent per hour (200?) and per day, so you may have exceeded those limits. The usual action is that you are frozen from sending for 24 to 48 hours, but may still open mails - just wait out the delay.
3. If you already are receiving the scrambled letters 'captcha' image to prove you are a human, your account is already under suspicion. You may have an infected computer which is using your account as a spam bot without your knowledge. To be sure your computer is not infected, run both an anti-virus and spyware/malware scans, updated and separately - even more than one malware scan, or Trend Micro's Housecall for an online a-v scan. (in 'Safe Mode with Networking' is the only truly effective method - click F8 repeatedly when the screen first lights on boot-up, then arrow keys and Enter to navigate.)
