Rails 2.3.2 Multipart Emails

I'm trying to send implicit multipart emails with Rails 2.3.2. I have
the files as in the past:

mailer_action.text.plain.erb
mailer_action.text.html.erb

When I run my tests, everything looks good. When I deliver email from
the console running in production mode, everything looks good. When
my controller calls the method, it uses the html template to send a
plain text email.

Anyone else seeing this behavior?

Thanks,
Tom

Okay, I've just verified that it is something to do with when Workling
(a queuing client). When Workling sends the email, it uses the html
template to create a plain text single-part email. Is there an
environment setting or something I need to specify somewhere?
