ruby 2.1 - Mail gets send from smtp username setting not from "from" method in ActionMailer rails -

in user_mailer.rb

class usermailer < actionmailer::base   default from: "email.1@gmail.com"   def approved_mail(user)     @user = user     @greeting = "hi"      mail to: @user.email   end end   

and in development.rb

config.action_mailer.smtp_settings = {   address: "smtp.gmail.com",   port: 587,   domain: "gmail.com",   authentication: "plain",   enable_starttls_auto: true,   user_name: "email.2@gmail.com",   password: env["gmail_password"] }   

i email "email.2@gmail.com" why not "email.1@gmail.com", waiting clarification guys.

in smtp_settings, need set user_name , password if our mail server requires authentication.

in case have provided authentication 'email.2@gmail.com' in development.rb file. hence action mailer ignore default from: "email.1@gmail.com" cannot authenticate it.
