Subject: Re: net/smtp Multiple Email recipients Issue

May I suggest you use Pony?

It is an added dependency but it makes creating emails and emails with 
attachments much easier.

I have below a program I've made that is very modular in that you pass 
in..
        - a email server address
        - a senders email address

from this you can call one of 2 methods to dispatch emails.
        - Emails with no attachments
        - Emails with attachments

I know these could be put into 1 but i've not got round to doing that.

For what it's worth the code is below....

 require 'pony'

 module Sendemail

    # call this 1st to setup the email server and senders
    # settings
    #
   def initial(server,address)
     @loginfo.info('setup email settings NOW...')
     @server = server
     @address = address
   end

     # this to send just an email
     #
   def send_email(from, to, subject, msg)
     @loginfo.info('sending an email - No Attachment sent !')

     Pony.mail(:to => "#{to}", :from => "#{from}", :subject => 
"#{subject}", :body => "#{msg}", :via => :smtp, :via_options => {
       :address => @server,
       :port => @address})

     @logbugs.debug("\nserver = #{@server}\nport used = #{@address}\nto 
= #{to}\nfrom = #from}\nsubject = #{subject}\nmsg = #{msg}")
   end
                                                                                # 
this to send with an attachment
     # Know the method and this one could be merged into one
     # I just haven't got round to it.
     #
   def email_attach(from, to, subject, msg,attachment,file_path)
     @loginfo.info('sending an email - Attachment sent !')

      # these 2 lines are so I can create a PDF via Prawn and add it as
      # the email - disregard these 2 lines
      #
     @table.pdf_setup filename,path,msg
     @table.tables

     Pony.mail(:to => "#{to}", :from => "#{from}", :subject => 
"#{subject}", :body => "#{msg}", :via => :smtp, :via_options => {
     :address => @server,
     :port => @address},
     :attachments => {"#{attachment}" => File.read("#{file_path}")})
     @logbugs.debug("\nserver = #{@server}\nport used = #{@address}\nto 
= #{to}\nfrom = #from}\nsubject = #{subject}\n
       msg = #{msg}\nfilename = #{file_path}")
   end
 end
