[Beowulf] Administrivia: emergency Mailman work for the Beowulf list

[Christopher Samuel]

Hi all,

The emergency work detailed below is now completed and 493 subscribers
have had their email re-enabled after it was disabled by bounces.

Users sending from sites that use DMARC will now have their From: header
rewritten to look like it comes to the list to stop this happening in
future, sorry about that.

All the best,
Chris
