Send emails with MS Exchange

config__initializers__send_emails.rb

# Use whatever your sysadmin says your settings are supposed to be
# ...
# ...

# The problem we had was that the SMTP server our outsourced sysadmin
# would send emails to Gmail, but they would not be received by the MS
# Exchange that he had set up for us. Our Rails mailer config was
# causing a spurious value in the SMTP "MAIL FROM" statement. This
# fixes it:

class ActionMailer::Base

  layout 'email'

  smtp_settings = # foo

# This WILL NOT WORK! It causes MAIL FROM <garbage@your_app_servers_hostname>
  default :sender => "Boppl"

# This works!
  default :sender => "Boppl <support@boppl.me>"
