David’s Thoughts

1) create a template file for your form, messages, and emails, based on example_form/mailformplus_demo.html
2) add a mailformplus record to a page
3) fill in send-to, subject, send-from, required-fields
3b) most importantly, attach the template file
3c) redirect-to-this-page seems not to work.
4) add a mailform plugin to the page (as content). No config needed on it.
5) add typoscript to template record:
plugin.tx_thmailformplus_pi1.emailHeader = Content-Type: text/html\r\n
plugin.tx_thmailformplus_pi1.emailParameter = -f server@host.example.com
