require 'mail/smtp_envelope'
module Mail
# A delivery method implementation which sends via sendmail.
#
# To use this, first find out where the sendmail binary is on your computer,
# if you are on a mac or unix box, it is usually in /usr/sbin/sendmail, this will
# be your sendmail location.
#
# Mail.defaults do
# delivery_method :sendmail
# end
#
# Or if your sendmail binary is not at '/usr/sbin/sendmail'
#
# Mail.defaults do
# delivery_method :sendmail, :location => '/absolute/path/to/your/sendmail'
# end
#
# Then just deliver the email as normal:
#
# Mail.deliver do
# to 'mikel@test.lindsaar.net'
# from 'ada@test.lindsaar.net'
# subject 'testing sendmail'
# body 'testing sendmail'
# end
#
# Or by calling deliver on a Mail message
#
# mail = Mail.new do
# to 'mikel@test.lindsaar.net'
# from 'ada@test.lindsaar.net'
# subject 'testing sendmail'
# body 'testing sendmail'
# end
#
# mail.deliver!
