Pony, the express way to send email in Ruby

Overview

Ruby no longer has to be jealous of PHP’s mail() function, which can send an email in a single command.

Pony.mail(:to => 'you@example.com', :from => 'me@example.com', :subject => 'hi', 
          :type => 'html', 
          :charset => 'windows-1252',
          :body => 'Hello there.')

Any option key may be omitted except for :to.

Default :type is ‘plain’ for “text/plain”, other option is ‘html’ Default :charset is set to ‘utf-8’

Transport

Pony uses /usr/sbin/sendmail to send mail if it is available, otherwise it uses SMTP to localhost.

This can be over-ridden if you specify a via option

Pony.mail(:to => 'you@example.com', :via => :smtp) # sends via SMTP

Pony.mail(:to => 'you@example.com', :via => :sendmail) # sends via sendmail

You can also specify options for SMTP:

Pony.mail(:to => 'you@example.com', :via => :smtp, :smtp => {
  :host   => 'smtp.yourserver.com',
  :port   => '25',
  :user   => 'user',
  :pass   => 'pass',
  :auth   => :plain # :plain, :login, :cram_md5, no auth by default
  :domain => "localhost.localdomain" # the HELO domain provided by the client to the server
}

TLS/SSL

With smtp transport it also possible to use TLS/SSL:

Pony.mail(:to => 'you@example.com', :via => :smtp, :smtp => {
  :host   => 'smtp.gmail.com',
  :port   => '587',
  :tls    => true,
  :user   => 'user',
  :pass   => 'pass',
  :auth   => :plain # :plain, :login, :cram_md5, no auth by default
  :domain => "localhost.localdomain" # the HELO domain provided by the client to the server
})

Attachments

You can attach a file or two with the :attachments option:

Pony.mail(..., :attachments => {"foo.zip" => File.read("path/to/foo.zip"), "hello.txt" => "hello!"})
