So, another challenge scenario:

1. #Wordpress #form sends email formatted with text tags to the mail server (#dovecot in my case as all internet parts are hosted on #Yunohost VPS)
2. Local server retrieves mail and parses text fields from the message.
3. Using preselected templates merges it with parsed text into a letter and envelope,
4. Upon confirmation of the operator, sends it all to the print spooler.

Am I missing anything? Are there any #FOSS programs doing such thing?
