EKM Tag: [ekm:captcha]
The CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) tag allows you to prevent unwanted spam emails being sent through your website email forms. The tag will output an addition field that requires the user to type 2 words, these words are distorted in a way that no computer would be able to read.
You must enable captcha on outgoing emails first. This can be done in Settings > Advanced Settings > Outgoing Emails
If you enable CAPTCHA and do not place the tag within your email forms the validation will fail and emails will not be sent.
