Every month I get an email from "mailman.opensound.com" reminding me of my subscription to the oss-devel mailing list. This email tells me I can go to http://mailman.opensound.com/mailman/options/oss-devel/timur%40freescale.com to modify my subscription.
The problem is that mailman.opensound.com does not exist. There is no DNS entry for this URL. Even if I use a third-party DNS lookup web site, like http://www.dnswatch.info/, it says that mailman.opensound.com is not a known address.

I also tried to send email to firstname.lastname@example.org, but that email bounced:

On a side note, it took me several tries to post this message because I could not read the confirmation code. It's just too hard to read it, and I kept getting it wrong.
