what is CAPTCHA ??

Yahoo! has enabled a challenge-response test to determine whether the user for Mail is human. "CAPTCHA" is an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart" trademarked by Carnegie Mellon University.

You may receive the CAPTCHA Send-Verify prompt if your message contains any of the following items:
  •  HTML
  •  Links
  •  Embedded graphics
  •  Attachments
  •  Forwarded messages (chain letters, jokes, etc.)
To confirm this, try sending a "Plain Text" message with no signatures or attachments to the same recipient. If you are not prompted with the CAPTCHA Send-Verify screen or the email arrives as expected, then the issue is most certainly related to one of the items listed.

Note: Please note that per the Yahoo! Mail Terms of Service  (TOS) the following are prohibited:
  •  Transmission of "junk mail," "spam," "chain letters," or unsolicited mass distribution of email.
  •  Transmission of material that is unlawful.
  •  Transmission of material that is harassing, abusive, threatening, harmful, vulgar, obscene, or invasive of another's privacy.
If the issue persists, please try sending a message using a PC and complete the CAPTCHA verification if prompted. If you do not have access to a PC, please let us know and we can send a message for you.
