It might not be as cool as having an email notification sent by an ifttt recipe executed in the cloud which in turn polls an RSS service regularly which is updated by incoming emails from openssl-announce, but it might just be a tad bit more reliable.
Careful with filters that send to email; on one occurrence (a Rails security advisory), it went to spam in gmail for many people. That's why I use a push notification app currently instead of email as a target.
