Maybe the filter discards all messages where the recipient email
address is not mentioned in a To: or Cc: header.

Maybe it's the Precedence: header.

I'd suggest having a careful look at the headers of the outgoing
messages.  It is possible for lists to be misconfigured in ways
that result in invalid (broken) headers.

If you're sure that your headers are all fine, talk with a sysop
of one of the receiving mailservers.
