Spurious emails from somewhere in "Debian hierarchy"

[Richard Owlett <rowlett@access.net>]

Since the beginning of February I've been receiving what I consider 
spurious emails.

I've set up a filter to send them to a separate sub-directory.
The filter detects either of 2 conditions:
  From,To,Cc or Bcc	Contains	bugs.debian.org
			*OR*
  To			Contains	www-master.debian.org


The only change to my setup {to best of my memory} was subscribing to 
the "debian-www@lists.debian.org" mailing list.

Where/how do I report this?
TIA
