This happened to me for a while with the standard majordomo installation.
What was going on was that the emails were grouped together so that multiple
addresses would be attached to a single email and if one of them were
undeliverable for some reason (like a mailhost somewhere being down), my
mail server would later try to re-deliver the message to the whole set
of addresses in the message, meaning most people would get multiple
deliveries.
I use a program called bulk_mailer to break out the messages so there's a
separate one for each domain being delivered to. Let me know if you need
a pointer to it, but it should be easy to google.
