I am trying to implement a very simple contact form using Sinatra, Pony and Sendgrid on the Cedar stack.
I keep getting the following error: Net::SMTPFatalError - 550 Cannot receive from specified address <pony@unknown>: Unauthenticated senders not allowed What should be in the 'from' part of the options? cheers, DAZ -- You received this message because you are subscribed to the Google Groups "Heroku" group.
