contact-form-7-dynamic-mail-to

.

This is exactly what I needed to use Contact Form 7 for sending mails from the site with the recipients chosen dynamically from a list of people. The plugin is less than 50 lines and works exactly as it should, and - despite the instructions which could have been clearer - it is really easy to use: just add a field in the contact form with the name a filter and add the filter (either in functions.php or a mini-plugin you write) to set the recipient address.
