We are continuing to monitor the situation.

Mailprotector is investigating and working with Yahoo in response to temporary deferred messages reported by Yahoo on their inbound mail systems. Anyone using Yahoo DNS may also see temporary delays. Mailprotector will continue to queue and attempt delivery until this issue is resolved.
