Patch for adding option to disable STARTTLS for ActionMailer SMTP connection

Hi all,

New in Rails 2.2 is a check to determine if the mail server responds to enable_starttls_auto. I submitted a patch for this Lighthouse ticket: #1491 SSL problem with SMTP in 2.2.2 - Ruby on Rails - rails

This is my first Rails patch submission, so any comments, suggestions or criticisms are greatly appreciated.

Thanks, Dan
