I'm unable to find any good documentation or examples of how to send an mail to an email address using Yesod.
More practically, I'll extract the information the user typed inside a simple form (name, age, body of message) and send this information as a mail to an email address.
I'm kind of lost in this task.
There are three packages I'd recommend you look at:
sendmail
executable.There is some discussion about sending email in the auth chapter of the Yesod book.
