[Mailman-Users] Mbox additions

[Keith Fischer]

Hi All,

I'm trying to "covertly" add a message to one of my lists archives.  It
appears to be possible by just editing the mbox file for that particular
list.  Can anyone point me to a simple resource for editing those files.
I know about running the arch app to update the archives afterward, I
just don't know how to get the email in the mbox in the first place.

I need to add an email that contains a PDF attachments.  

Thanks
Keith
