[DRE-maint] Dubious subscription notification

[Jörg-Volker Peetz]

Dear maintainers(s),

recently, I receive a lot of e-mails with subject beginning with "[DRE-maint] ".
The two last ones about subscription confirmation and a "web subscription for
coderay package", which I definitly not sent.
Could you please give me some information how to unsubscribe from all these
mailing lists?
