subscribe to xorg-announce mailing list

I'd like to subscribe (had forgotten that I was not subscribed) to followup on libXt 1.2.0

The auto-subscribe/confirm is not working for xorg-announce. Here's what I get back:

<xorg-announce-request@lists.x.org>: host gabe.freedesktop.org[131.252.210.177]
    said: 550 5.1.1 <xorg-announce-request@lists.x.org>: Recipient address
    rejected: User unknown in local recipient table (in reply to RCPT TO
    command)

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
