This is a known issue for some years now. We're currently running
Mailman 2.1.14 as packaged in Ubuntu 12.04 LTS. If we get some
volunteers to work within the Infra team to help us move to a later
release of Mailman, there are a number of options at our disposal to
help address this issue. In the interim, the alternative
recommendation is to not subscribe to the list from addresses at
sites enforcing DKIM/DMARC for forwarding/delivery.
