For the past few days our exchange server has not been sending emails to anyone at a yahoo email. I have logged into the System Manager for exchange and noticed there are 90 messages in the queue for yahoo and a few other emails for other domains. The queue has been like that for a while, and I can try to unfreeze, but it doesnt do anything.
Any ideas why this would be happening? I have a comcast domain and if I send an email to myself it shows up right away as does gmail and many other domains, but yahoo and these others that I am seeing in the queue are just sitting there not going anywhere. Every once in a while emails will get sent out, but it takes forever.
What should I do to fix this so it goes right away?
