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', :body => 'Hello there.')
Pony.mail(:to => 'you@example.com', :html_body => '<h1>Hello there!</h1>', :body => "In case you can't read html, Hello there.")
Pony.mail(:to => 'you@example.com', :cc => 'him@example.com', :from => 'me@example.com', :subject => 'hi', :body => 'Howsit!')

Any option key may be omitted except for :to. For a complete list of options, see List Of Options section below.

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,
  :via_options => {
    :address        => 'smtp.yourserver.com',
    :port           => '25',
    :user_name      => 'user',
    :password       => 'password',
    :authentication => :plain, # :plain, :login, :cram_md5, no auth by default
    :domain         => "localhost.localdomain" # the HELO domain provided by the client to the server
  }
})

Gmail example (with TLS/SSL)

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

And options for Sendmail:

Pony.mail({
  :to => 'you@example.com',
  :via => :sendmail,
  :via_options => {
    :location  => '/path/to/sendmail', # defaults to 'which sendmail' or '/usr/sbin/sendmail' if 'which' fails
    :arguments => '-t' # -t and -i are the defaults
  }
})

If you’re using ssmtp, set :arguments => ''.

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!"})

Note: An attachment’s mime-type is set based on the filename (as dictated by the ruby gem mime-types). So ‘foo.pdf’ has a mime-type of ‘application/pdf’

Custom Headers¶ ↑

Pony allows you to specify custom mail headers

Pony.mail(
  :to => 'me@example.com',
  :headers => { "List-ID" => "...", "X-My-Custom-Header" => "what a cool custom header" }
)

Add additional options for headers in each part of letter (text, html)

Pony.mail(
  :body => 'test',
  :html_body => 'What do you know, Joe?',
  :attachments => {"foo.txt" => "content of foo.txt"},
  :body_part_header => { content_disposition: "inline" }
)

This will add option ‘Content-Disposition: inline’ for text part header of letter.

Also you can add additional options for html part of latter, e.g.:

:html_body_part_header => { content_disposition: "inline" }

List Of Options¶ ↑

Options passed pretty much directly to Mail

to
cc
bcc
from
body # the plain text body
html_body # for sending html-formatted email
subject
content_type
charset # In case you need to send in utf-8 or similar
text_part_charset # for multipart messages, set the charset of the text part
attachments # see Attachments section above
headers # see Custom headers section above
body_part_header # see Custom headers section above
html_body_part_header # see Custom headers section above
message_id
sender  # Sets "envelope from" (and the Sender header)
reply_to
smtp_envelope_to

Other options

via # :smtp or :sendmail, see Transport section above
via_options # specify transport options, see Transport section above

Set default options¶ ↑

Default options can be set so that they don’t have to be repeated. The default options you set will be overriden by any options you pass in to Pony.mail()

Pony.options = { :from => 'noreply@example.com', :via => :smtp, :via_options => { :host => 'smtp.yourserver.com' } }
Pony.mail(:to => 'foo@bar') # Sends mail to foo@bar from noreply@example.com using smtp
Pony.mail(:from => 'pony@example.com', :to => 'foo@bar') # Sends mail to foo@bar from pony@example.com using smtp

Help¶ ↑

External Dependencies¶ ↑

mail > 2.0

Note: these requirements are specified in the gemspec as well. Also, you may need smtp_tls if you want to send via tls/ssl and are using ruby < 1.8.7
