config/environments/$RAILS_ENV.rb 中只能设置一个发送服务器
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => 'baci.lindsaar.net',
:user_name => '<username>',
:password => '<password>',
:authentication => 'plain',
:enable_starttls_auto => true }
怎么才能设置多个,比如 [email protected], [email protected], [email protected] ...
