Question

I’m trying to send emails but the emails will never use my :from => code, instead the email always arrives using the ‘from’ of my gmail smtp settings. So for example the email arrives and says FROM: [e-mail] instead of FROM: [e-mail] , and in the logs it shows the email sent using the FROM: [e-mail] which is from my devise initializer.

How can I fix this? Its really upsetting at the moment 🙁 Thanks for any help.

I’m using Gmail and setup my smtp settings like this:

config/initializers/mailer_setup

ActionMailer::Base.smtp_settings = {
     :address              => "smtp.gmail.com",
     :port                 => 587,
     :domain               => "mydomain.com",
     :user_name            => "[e-mail]",
     :password             => "mypassword",
     :authentication       => "plain",
     :enable_starttls_auto => true
     }

mailer/user_mailer.rb

   def reset_password_instructions(user)
     @user = user
     @url  = "http://localhost:3000"
     mail(:to => user.email,
          :from => "[e-mail]",
          :subject => "recover your password"
          )
   end
end

Gmail is changing your from. Get your own mailserver if you don’t want modifications.

There is a guide on how to set a different sender when using the mail interface and/or googles servers.

Note for IMAP/POP users: If you access Gmail through a POP or IMAP email client (e.g. Outlook) and would like to send messages with a custom “from” address, you have two options. We recommend that you configure your email client with two outgoing SMTP servers, one for Gmail and one for your other address. Or, you can use Gmail’s outbound servers with a different “from” address. If you’ve already configured the alternate address, your message will be sent from:[e-mail], sender:[e-mail], regardless of which custom from configuration you chose.

You have to enable your 3rd party address for gmail first. Check the guide linked above.
IIRC gmail will set the different address, however the users will still see that its coming from gmail.
