Sending Emails In Ruby

To send emails using ruby you can use the Net::SMTP library. In the following example from_addr is a String that represents the source email address to_addr is also a String. It can also be an Array of strings if you want to send the email to multiple recepients.

Code: Ruby

require 'net/smtp'

  Net::SMTP.start('smtp.example.com', 25) do |smtp|

    smtp.open_message_stream('from_addr', [to_addr]) do |f|

      f.puts 'From: shabbir@g4ef.com'

      f.puts 'To: pradeep@g4ef.com'

      f.puts 'Subject: test message'

      f.puts 'This is a test message.'

    end

  end

SMTP Authentication

If you need to authenticate before sending mails then Net::SMTP class supports three authentication schemes; PLAIN, LOGIN and CRAM MD5. (SMTP Authentication: [RFC2554])

Code: Ruby

# PLAIN

  Net::SMTP.start('your.smtp.server', 25, 'mail.from.domain','Your Account', 'Your Password', :plain)

  

  # LOGIN

  Net::SMTP.start('your.smtp.server', 25, 'mail.from.domain','Your Account', 'Your Password', :login)

  

  # CRAM MD5

  Net::SMTP.start('your.smtp.server', 25, 'mail.from.domain','Your Account', 'Your Password', :cram_md5)
