The MTA. Except at VGER there is special static routing rule asked from Demon folks for dumping there all *.demon.co.uk subdomains. That static route puts them all to punt-2.mail.demon.net.
At VGER's lists there are currently 455 recipients which are at various (sub)domains under demon.co.uk.
This method makes them transported from VGER in one SMTP transaction per message instead of 46 separate (for linux-kernel list, other lists have other counts..)
