Comcast/Yahoo Mail - now functional

We've been cleared by Comcast and Yahoo, and all messages that were queued up have been delivered. Delivery of new messages is back to normal, except we may be blacklisted on one or more listing services. We will address those as we encounter them. If you receive any "bounceback" error messages when attempting to send an Email, please forward them to the Helpdesk and we will work with the receiving side to resolve them all.
