Sinatra with Pony always has the same email for from - email

Question

I'm working through a contact form from Sinatra Jump Start and trying to figure out why the "From" is always the same gmail account I'm using as the :user_name. I have an Heroku version and it's also always the same :from. My goal is to have the little contact form where there is Name, Email and Message send to the receiving email and the "From" would be the sender's Name and Email.
I thought maybe this is because of local version, but it's the same result on Heroku. The setting for :user_name ends up as the "From" I'm doing something wrong, any ideas?
Is the :from => params[:name] + "<" + params[:email] + ">" that's no longer correct, the book I'm working from isn't too old.
Here's what my contact.slim form looks like:
p You can contact me by filling in the form below:
form class="contact" action="/contact" method="POST"
p
label for="name" Name:
input type="text" name="name"
p
label for="email" Email:
input type="text" name="email"
p
label for="message" Your Message:
textarea name="message"
input type="submit" value="Send Message"
Here's my send_message:
def send_message
Pony.mail(
# this always comes back as the same gmail.account I'm using for the :user_name
:from => params[:name] + "<" + params[:email] + ">",
:to => 'mygmail#gmail.com',
:subject => params[:name] + " from #{params[:email]} has contacted you ",
:body => params[:message],
:via => :smtp,
:via_options => {
:address => 'smtp.gmail.com',
:port => '587',
:enable_starttls_auto => true,
:user_name => 'mygmail#gmail.com',
:password => 'mypassword',
:authentication => 'plain',
:domain => 'localhost.localdomain'
})
end
And my post route handler from my main.rb
post '/contact' do
send_message
flash[:notice] = "Thank you for your message. We'll be in touch soon."
redirect to("/")
end
Then when I tried on Heroku for I have this in the main.rb:
configure :development do
# for the local MySQL db
DataMapper.setup(:default, 'mysql://root:admin#localhost/sinatra_jumpstart')
set :email_address => 'smtp.gmail.com',
:email_user_name => 'mygmail#gmail.com',
:email_password => 'mypassword',
:email_domain => 'localhost.localdomain'
end
configure :production do
# for Heroku
DataMapper.setup(:default, ENV[ 'DATABASE_URL' ])
set :email_address => 'smtp.sendgrid.net',
:email_user_name => ENV['SENDGRID_USERNAME'],
:email_password => ENV['SENDGRID_PASSWORD'],
:email_domain => 'heroku.com'
end
Update: It seems like if my goal is to be able to reply-to, there's a :reply_to option that I can pass the params[:email] to, but that still leaves me wondering why the 'From' show the name (coming from params[:name]) correctly, but ignores the params[:email] for the 'From' email address and instead shows my :user_name email from the :via_options instead.

Answer 1

This answer came from a sitepoint discussion.
You are sending the form from your webpage and so the sender is yourself.
If you were opening the senders email software ( using the html mail function? ) and the user was sending from that it would have their email address.
This happens a lot in forums when the user gets an email from another user and uses "reply". The email is then sent to the forum admin. There is usually a note on the message saying something like "Do not reply to this message but do so in the forum messaging section".
