    Default postmaster 550-mailbox

    I attempted to send an email this morning (via Zimbra 3.1.x) and my message was rejected with the following error information:

    host[] said: 550-Postmaster verification failed while checking <> 550-Called: 550-Sent: RCPT TO:<> 550-Response: 550 <>: Recipient address rejected: 550-Several RFCs state that you are required to have a postmaster 550-mailbox for each mail domain. This host does not accept mail 550-from domains whose servers reject the postmaster address. 550 Sender verify failed (in reply to RCPT TO command)
    Any ideas here? We are about to upgrade to Zimbra 4, so would that resolve the issue?

    Here's what Sourceforge says about it:

    Do you have a account?
    (where, is your MX record).

    (Zimbra generally creates one directing to admin)

    (Yet another ZIMBRAN!)
