[Mailman-Users] Editing values in a lists's config.pck file?

I need to change the gate_news watermark on one of my mailing lists, as it got incremented without a message actually being gatewayed from the usenet newsgroup to the mailing list (because of something to do with the "list" user's password having expired and cron).

I am using mailman 2.1.5-8sarge5.

I found that this information is contained in the list "config.pck" file:

# /var/lib/mailman/bin/dumpdb /var/lib/mailman/lists/<listname>/config.pck
| grep -i watermark 'usenet_watermark': 10,

What I want to do here is change usenet_watermark to 9; however I haven't been able to find any information on how to modify the config.pck file - anyone know how that would be done?

Thanks,
