Example showing how to create a Mail::Message and extract bcc addresses, html, and plain body

mail.rb

# build an email
mail = Mail.new do
  to      '[email protected]'
  from    '[email protected]'
  bcc     ['[email protected]','[email protected]','[email protected]']
  subject 'test email'
end

text_part = Mail::Part.new do
  body 'This is plain text'
end

html_part = Mail::Part.new do
  content_type 'text/html; charset=UTF-8'
  body '<h1>This is HTML</h1>'
end

mail.text_part = text_part
mail.html_part = html_part

mail.delivery_method :smtp, address: "yourserver.example.com"

# deliver the email
mail.deliver

# extract the list of bcc addrs
Mail::AddressList.new(mail.header[:bcc].decoded).addresses.each do |bcc|
  puts "looks like you want to bcc '#{bcc}'"
end

# extract the html body
html_body = mail.parts.detect{|p|p.content_type =~ /text\/html/}
html = html_body ? html_body.body.raw_source : ""

# extract the plain body
plain_body = mail.parts.detect{|p|p.content_type =~ /text\/plain/}
plain = plain_body ? plain_body.body.raw_source : ""
