I am trying to volunteer to help maintain the appdb, but mail to appdb@winehq.com bounces with the error below.  I have emailed this address successfully before.  Has it been removed?  If not, is there a known (or perhaps unknown) problem?
 
<appdb@winehq.com>:
198.144.15.226 does not like recipient.

Giving up on 198.144.15.226.
