# 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'
