    Default 550 #5.7.1 Your access to submit messages to this e-mail system has been rejected.

    Last week we noticed some emails not leaving the Exchange queue and now this week they are getting blocked right away from the exchange server. I am pretty sure that this in on the Recieving end as we can email everyone else just fine.

    As Frontier has purchased Verizon's Telephone and Internet services earler this year and are just now moving servers and rearranging NOC's. I see a mess comming our way.

    *** Virus defs are current on all computers.
    *** Verified twice yesterday.
    *** Not listed on any RBL.
    *** Sent an unblock request to Frontiernet.

    Here is some changed header information from the bounceback.

    My first thoughts:
    • rDNS
    • You're listed on one or more block-lists.
    • You've previously sent e-mail to a non-existent account on their system.
    I seem to recall issues where Frontier and rDNS was the cause of that in the past.

    This isn't good - Received: from localhost.localdomain ([127.0.0.1] helo=localhost)

    I agree with Jamroar. Plus FYI the non-existent account would be a honeypot spam trap most likely.
