Question about mailfactory

I am using the mailfactory from rubyforge. It seems to work well.
Was wondering how best to reuse the object I created with it. There
does not seem to be a reset or finish method. Do I need to destroy
the object after sending an email (dont know how to destry objects but
can look this up). The main thing is I am adding a attachment so just
removing all attachments would do the trick.

I wouldn’t be to bothered but it is a loop and I think that every time
I loop round I am creating a new object.
