here you recommended flamingo plugin to use with contact form. - BE AWARE phishing scheme
After installing I've been contacted by my hosting provider Network Abuse Department and they said that my account has been implicated in a phishing scheme
and i had to remove next files
wp-includes/js/scriptaculous/update.php
wp-includes/js/scriptaculous/logon.php
wp-includes/js/scriptaculous/NBmain.html
wp-includes/js/scriptaculous/Challenge.html
mass mailer needs to be removed
wp-content/plugins/flamingo/black.php
shell
wp-content/plugins/flamingo/blackenemy.php
So i have a very bad experience with this plugin and do not recommend it
