问题
Trying to rewrite an old alias_method_chain to add a filter on outgoing emails, and it isn't working. I'm pretty sure I've leaving something out/missing something, but I don't know what.
This file is in /lib/outgoing_mail_filter.rb, which is loaded with config/initializers/required.rb
Here's the old code that worked under Rails 2:
class ActionMailer::Base
def deliver_with_recipient_filter!(mail = @mail)
unless 'production' == Rails.env
mail.to = mail.to.to_a.delete_if do |to|
!(to.ends_with?('some_domain.com'))
end
end
unless mail.to.blank?
deliver_without_recipient_filter!(mail)
end
end
alias_method_chain 'deliver!'.to_sym, :recipient_filter
end
And here's my current attempt at re-writing it:
class ActionMailer::Base
module RecipientFilter
def deliver(mail = @mail)
super
unless 'production' == Rails.env
mail.to = mail.to.to_a.delete_if do |to|
!(to.ends_with?('some_domain.com'))
end
end
unless mail.to.blank?
deliver(mail)
end
end
end
include RecipientFilter
end
When I run my tests, it doesn't even look like this is being called or anything. Any help is appreciated

I'm using mail_safe to rewrite emails in the development environment, highly recommended. You could look into it for inspiration if it doesn't fit your bill, the code is very simple.
The following code is extracted from /lib/mail_safe/rails3_hook.rb and should do what you want:
require 'mail'
module MailSafe
class MailInterceptor
def self.delivering_email(mail)
# replace the following line with your code
# and don't forget to return the mail object at the end
MailSafe::AddressReplacer.replace_external_addresses(mail) if mail
end
::Mail.register_interceptor(self)
end
end
Alternate version, registering with ActionMailer::Base
instead of Mail
(thanks to Kevin Whitaker for letting me know it's possible):
module MailSafe
class MailInterceptor
def self.delivering_email(mail)
# replace the following line with your code
# and don't forget to return the mail object at the end
MailSafe::AddressReplacer.replace_external_addresses(mail) if mail
end
::ActionMailer::Base.register_interceptor(self)
end
end
