I think the new email package should work without change (or with very
little change) with 2.2.1.  In fact I believe the intention is to
backport the new email package to 2.2.2.  But I don't want to import
the entire email package into the spambayes CVS tree.

I've checked the uses of get_type() (all in tokenizer.py), and I
believe that they all do the right thing except possibly one.  This
code:

            # Remove HTML/XML tags.
            if (part.get_type() == "text/plain" or
                    not options.retain_pure_html_tags):
                text = html_re.sub(' ', text)

should become:

            # Remove HTML/XML tags.
            if (part.get_type('text/plain') == "text/plain" or
                    not options.retain_pure_html_tags):
                text = html_re.sub(' ', text)
