Forwards not working anymore!

Forwards not working anymore!

I have two different forwarded accounts we use for our business, and they are not working!  This is critical to us...

I sent two different e-mails at 11:42 am and 11:30 am.  Neither arrived.  Luckily, I just received an e-mail from a client, but it was back-dated 27 minutes ago.

Help?
