[Mailman-Users] bcc problem

[o omida parasita]

When using an email list if you send a message to the list but also do
a bcc /cc the message gets sent to moderator.

So for example we have a private list for internal use:

production at domain.com

If I (a member of the list) send a message to production at domain.com and I
bcc john at anotherdomain.com, the message gets sent to the moderator for
approval. I would get a message saying that the message is being held until
the list moderator can review it for approval.

The reason it is being held:

Message has implicit destination


Is there a way to disable this feature/problem?
