Rails - Nov 2006 - setting email headers so gmail formats email correctly

Hey guys,

I''m trying to format my email so that, my html email shows up correctly
when a user sees their email through gmail.com. Here is what I have so
far:

   def invite(email="", sender = "")
      @subject    = sender.full_name + '' has invited you to
Mixbook.com''
      @recipients = email
      @from       =
''invite-yyL2eFK7MhNBDgjK7y7TUQ@public.gmane.org''
      @sent_on    = Time.now
      @content_type="text/html"
      @headers    =
{"MIME-Version"=>1.0,"Content-Type"=>"text/html"}
      @body[''sender''] = sender
   end

This seems to be working when I send I see the email through outlook
express. What am I missing here. I noticed that the gmail emails that
work correctly use "multipart/alternative." Is there some kind of
trick
that I am missing?

I doubt that is going to work like you want it to. "Sender:" is a
fairly magical header that''s used by MTAs to let MUAs know which
envelope sender was used, so depending on the exact details of your
mail setup that line may work as you intend, be deceptive or be
overwritten.

For my own application, I wrote a tiny plugin that monkeypatches
ActionMailer to allow setting the sender as it should be (in the SMTP
dialog for :smtp, with -f for :sendmail). I don''t have a public svn
server to easily publish it from, but I could post it here, I guess.
If there''s interest.

Oh the @body[''sender''] = sender shouldnt effect anything. That
just
insures that I have an @sender variable in my body to make the email, it
doesnt go in the headers...

Duh. Of course. I blame lack of caffeine.

Anyway, if anyone is interested in the plugin to set the real sender,
it''s on http://rubyforge.org/projects/amsenderplugin/ now.

i went to your link to check out the plugin, it says there are no files 
there. Can you upload them or point me to where they are?

Hmm, I think your plugin might be a little too elaborate. I just need to 
enable all mail programs to be able to read the text/html emails i make. 
I think this involves setting a multipart/alternative content type along 
with entering some things into the headers. Anyone here successfully 
created text/html with actionmailer that can be read through gmails 
website, it cant be that hard. =) Thanks in advance.

Rails Recipes has a recipe for exactly this case.  Here''s a snippet
that can help you along the way:

def multipart_alternative(recipient, name, sent_at = Time.now)
  ...
  content_type "multipart/alternative"
  part :content_type => "text/plain",
    :body => render_message("multipart_alternative_plain", :name
=>
name)

  part :content_type => "text/html",
    :body => render_message("multipart_alternative", :name =>
name)
end

It''s all in the anonymous SVN repo for the project:

Im having a lot of problems with this. With gmail, it rendering the 
email incorrectly.

Here is my code:

class InviteMailer < ActionMailer::Base

   def invite(email, sender)
      subject    sender.full_name + '' has invited you to
Mixbook.com''
      recipients email
      from      
''invite-yyL2eFK7MhNBDgjK7y7TUQ@public.gmane.org''
      sent_on    Time.now
      #content_type "multipart/alternative"
      headers  = 
{"MIME-Version"=>1.0,"Content-Type"=>"multipart/alternative"}
      body ''sender'' => sender

      #part :content_type=> "text/plain",
       #  :body =>
render_message("invite_plain",:sender=>sender)

      part :content_type=> "text/html",
         :body => render_message("invite", :sender=>sender)
   end
end


Here is the email information it produces:

Don''t know if this is what''s causing your problems, but GMail
removes a
lot of HTML formatting, which other programs leave in.  It''s pretty
near
impossible to get an HTML email to a GMail account to come out looking 
like you intend.  Check out 
http://www.campaignmonitor.com/blog/archives/2005/11/html_email_desi.html 
for ideas on working around mail readers'' issues.

thats correct, but in the above code you''ll notice the mail headers get
changed, not just wants in the email. Also, facebook sends html messages 
that come out fine, so i know its possible. Anybody have any ideas?

I checked out that site, it doesnt seem to help with this problem. Maybe 
there is a setting I am missing when I initialize actionmailer?

Eric,

I don''t know if this will help you but I ran into trouble with my
emails
as well and posted a solution to my misery here:

http://www.ruby-forum.com/topic/83988#150502

I ended up base64 encoding the html portion of my emails.

Perhaps it will help.

Best Regards,

Steven
