Have you been able to see a pattern separating those can get sent and
those that don't?

Wild guess: You do tarpitting (or other "answer slowly to suspected
spammers" measure) in your MTA and localhost is not whitelisted
(exempted) from this.

If you send the same email Mailman is sending, does it go through? I
mean when you send it with SMTP, not by piping to /usr/sbin/sendmail.

I don't know. Mark Sapiro claims that smtplib debug info goes to
stderr, but it goes to stdout. Maybe this explains it. On the other
hand, writing to stderr creates a traceback.
