Rails - Jul 2005 - ActionMailer duplicates output

I am using ActionMailer to send comments submitted from the site.  In
app/models/mailer.rb, I have:

  def comments(name, email, comments_text, sent_at = Time.now)
    @subject    = ''Mailman#comments''
    @body       = { "name" => name, "email" => email,
"comments_text"
=> comments_text }
    @recipients = admin-+LBmYUDmh58@public.gmane.org
    @from       = email
    @sent_on    = sent_at
    @headers    = {}
  end

And in app/views/mailer/comments.rhtml:

From: <%= @name %>
Email: <%= @email %>
Comments:

<%= @comments_text %>


However, when I recieve an email, it looks like it was generated using this:

From: <%= @name %>
Email: <%= @email %>
Comments:

<%= @comments_text %>

Comments:

<%= @comments_text %>

In other words, the comments section is duplicated, but only the
comments section.  What am I doing wrong here?
