mail.html: russian maillist seems to be dead

Hi,

I tried to subscribe to the russian openbsd maillist and my request
wasn't even delivered. Maybe it is a temporary issue, but for now
the domain openbsd.ru doesn't even resolve to any IP address.

So probably the following information on mail.html may be considered
outdated:

Russian: [email protected]
To subscribe, send mail to [email protected] with subject
"subscribe openbsd".
