Issues sending to

I manage the email system for a school district with over 1600 users. For the past three months or so my outbound email queue just to addresses stops delivering, displaying "451 4.4.0 SMTPSEND.SuspiciousRemoteServerError; remote server disconnected abruptly; retry will be delayed."

Although restarting my Exchange servers has been the only resolution to date, there has to be a better way. Since is the ONLY domain to which we have any trouble sending, and I know there are plans to move to AOL on their backend, I can't help but think something is going on at Verizon to cause this.

Since our community has a HUGE FiOS subscriber base, it is imperative that email flow out to our parents and community members. Any help on this situation would be appreciated.
