When converting a mailing list to mailman, I copied the mailbox (which contained the mailing list discussions in the mbox format) to the necessary location, deleted the old archive and generated a new one with bin/arch. However, this ignored many mails in the mail box. The reason was the "^From " line had an extra time specifier (something like +0600) at the end. I had to filter the mailbox through

sed 's/\(^From .*\) [-+][0-9][0-9][0-9][0-9]$/\1/'

to remove them, and after that all the mails were added to the archive without problems.

Please make mailman work with such mail boxes, because this is the easiest way to convert an already running mailbox to Mailman.

Also I noticed that the email bug-mailman@gnu.org doesn't work. It reaches python.org and comes back.
