[boost] mail problems

Hello. Seems like boost mailing totally refuses to work with my "ardatur at mail dot ru" address... A couple of months ago I had to resubscribe as <the "from" address> because of this (http://lists.boost.org/mailman/options.cgi/boost/@@@ reported bounces from the destination address), and now I can't register at the vault using the "ardatur at mail dot ru" address (no activation mail). Is that fixable? -- Best regards, Vladimir Pozdyayev.
