The previous mail by the "Mail Administrator"is a spoof:
*** don't open it ***
it probably contains a virus or something that harms your computer, it
has never been sent by anyone in dyne.org (no signature and headers
included as a proof) and it won't happen again.

sorry for the inconvenience, but consider that this mailinglist is
targeted by more than 200 mails *daily* from spammers and fishers.
me and other skilled sysadmins in dyne are doing our best to resist.

ciao
