Sendmail is not ignoring MX lookups

Question

I recently learned of the joys of square brackets with SMART_HOST to have sendmail ignore MX lookups. I need this functionality, however, I can't seem to make it persistant. Sending mail with -Am works, however, -bm does not. In the -Am case, the correct mail server is used. In the -bm case, an MX lookup is still being performed. Is there a way to disable MX lookups (or some working alternative)?

Thanks

You can use Sendmail's mailertables feature to override MX records on a per domain basis.
