I haven't received an email from StoryBoard for a few weeks now. While I'm quite enjoying the silence, it's probably not productive... I'm subscribed to a few projects and have email notifications checked in preferences. Is it just me?

It appears that Rackspace has recently added the surrounding IPv4 /22 CIDR to the Spamhaus Policy Block List: https://www.spamhaus.org/pbl/query/PBL1660430 As a result, the receiving MTA is rejecting E-mail from the server destined for your domain. I have filed with Spamhaus to get a PBL exception added for this specific IP address, which should take effect within the next hour. Sorry to say, you'll probably start finding out about more bugs! ;) (Also, huge thanks for bringing this to our attention.) -- Jeremy Stanley
