    I have two servers clustered and everything seems to work okay except for email between certain accounts located on the opposite server.

    For example is located on server 1, and it can send and receive email from any site except for email accounts located on server 2 and vise versa.

    This seems to happen when one of the clients is using an email account on an addon domain.

    I can ping the domain correctly from either server, the sites load correctly from all associated domains, and I can email to/from the accounts using any email account not located on the opposite server.

    Has anyone seen this?

    The bounce error message is:
    SMTP error from remote mailer after RCPT TO:<>:
    host []: 550-Verification failed for <>
    550-Unrouteable address
    550 Sender verify failed
