I've just moved the blog from blosxom (no longer developed or supported, it seems) to Nikola. Importing the old data proved to be easy, I used import_feed I've also fixed the mailer form, it must have broken when the HTTP "referer" (sic) header was lost. A lot simpler, no need for "BareBonesMailer" (which has disappeared totally from the Internet), just use the "mail" facility in PHP.
