[Mailman-Users] Importing messages to archives

Okay, now we're half way home. The messages that I pasted in are all now
visible in the archives for the appropriate time, but every one is listed as
"No subject" and when you read them all of the original headers are

There is a valid subject line, I'm replacing the three-letter name of the
previous list with ABC:

     Subject: [ABC] Detailed Charge Master Report

Ass opposed to the same header if I send it in directly:

     Subject: [Test] test to look at headers

So, do I need to replace headers on the additional messages to make this
work? Or should it have already worked?
