I just installed the restful\_authentication plugin and did a generate with :include-activation. Whenever i signup i get the following error: Net::SMTPSyntaxError in UsersController#create 504 : Sender address rejected: need fully-qualified address What does this mean? I have the actionmailer configurations right i think: i created a mailer class in the same app for testing and those mails are being delivered without any problems. ---
