Subject: Re: Send email with attachments in Ruby

Here's updated code using sendmail and Dir.glob instead of FileList:

require 'rubygems'
require 'action_mailer'
require 'mime/types'

ActionMailer::Base.delivery_method = :sendmail
ActionMailer::Base.default_content_type = "text/plain"

class Mailer < ActionMailer::Base
  def message (from, to, title, body, attachments)
    from from
    recipients to
    subject title
    body body

    Dir.glob(attachments).each do |path|
      file = File.basename(path)
      mime_type = MIME::Types.of(file).first
      content_type = mime_type ? mime_type.content_type : 
'application/binary'
      attachment (content_type) do |a|
        a.body = File.read(path)
        a.filename = file
        a.transfer_encoding = 'quoted-printable' if content_type =~ 
/^text\//
      end
    end
  end
end

Mailer.deliver_message 'Christopher Pickslay <from@somedomain.com>',
   'to@somedomain.com',
   'Some reports',
   "See attached tab-delimited reports\n\n",
   '/tmp/reports/*.txt'
